From left, co-coach Nick Brighton, sophomores Shloke Kamat and Timothy Chen, juniors Feodor Yevtushenko and Angelina Yan, senior Sara Yu, and coach David Knight.NASA/JPL-Caltech In a fast-paced competition, students showcased their knowledge across a wide range of science and math topics. What is the molecular geometry of sulfur tetrafluoride? Which layer of the Sun is thickest? What is the average of the first 10 prime numbers? If you answered “see-saw,” “radiation zone,” and “12.9,” respectively, then you know a tiny fraction of what high school students must learn to compete successfully in the National Science Bowl. On Saturday, March 1, students from University High School in Irvine answered enough of these kind of challenging questions correctly to earn the points to defeat 19 other high school teams, winning a regional Science Bowl competition hosted by NASA’s Jet Propulsion Laboratory in Southern California. Troy High, from Fullerton, won second place, while Arcadia High placed third. Some 100 students gathered at JPL for the fast-paced event, which drew schools from across Los Angeles, Orange, and San Bernardino counties. Teams are composed of four students and one alternate, with a teacher serving as coach. Two teams at a time face off in a round robin tournament, followed by tie-breaker and double-elimination rounds, then final matches. Students, coaches, and volunteers gathered on March 1 for the annual regional Science Bowl competition held at JPL, which has hosted the event since 1993.NASA/JPL-Caltech The questions — in biology, chemistry, Earth and space science, energy, mathematics, and physics — are at a college first-year level. Students spend months preparing, studying, quizzing each other, and practicing with “Jeopardy!”-style buzzers. It was the third year in a row for a University victory at the JPL-hosted event, and the championship round with Troy was a nail-biter until the very last question. The University team only had one returning student from the previous year’s team, junior Feodor Yevtushenko. Both he and longtime team coach and science teacher David Knight said the key to success is specialization — with each student focusing on particular topic areas. “I wake up and grind math before school,” Feodor said. “Being a jack-of-all-trades means you’re a jack-of-no-trades. You need ruthless precision and ruthless speed.” University also won for four years in row from 2018 to 2021. The school’s victory this year enables its team to travel to Washington in late April and vie for ultimate dominance alongside other regional event winners in the national finals. More than 10,000 students compete in some 115 regional events held across the country. Managed by the U.S. Department of Energy, the National Science Bowl was created in 1991 to make math and science fun for students, and to encourage them to pursue careers in those fields. It’s one of the largest academic competitions in the United States. JPL’s Public Services Office coordinates the regional contest with the help of volunteers from laboratory staff and former Science Bowl participants in the local community. This year marked JPL’s 33rd hosting the event.

NASA In this 1957 photo, George Cooper, a test pilot for the National Advisory Committee for Aeronautics, or NACA, stands next to a North American F-100, a supersonic fighter tested by the NACA. Cooper served as a pilot in World War II before being hired at the NACA’s Ames Aeronautical Laboratory in 1945. Between 1945 and his retirement in 1973, Cooper tested over 135 aircraft, routinely pushing them to their limits. On March 3, 1915, the NACA was established by Congress to “supervise and direct the scientific study of the problems of flight, with a view to their practical solution.” Over the course of its 43 years, the NACA became home to many of the nation’s best and brightest aeronautical engineers and world-class facilities. America’s flight capabilities for military and commercial uses were advanced through its cutting-edge research. It was upon this foundation that America’s civilian space agency was built. With the passing of the Space Act in 1958, the NACA was transformed into NASA and tasked with researching problems of flight in both the air and in space.

Preventing biofilm formation in space Ashley Keeley, University of Idaho, holds an anti-bacterial coating sample.University of Idaho Student Payload Opportunity with Citizen Science Team Two anti-microbial coatings reduced formation of biofilms in microgravity and have potential for use in space. Controlling biofilms could help protect human health and prevent corrosion and degradation of equipment on future long-duration space missions. Biofilms, communities of microorganisms that attach to a surface, can damage mechanical systems and present a risk of disease transmission. Bacteria Resistant Polymers in Space examined how microgravity affects polymer materials designed to prevent or reduce biofilm formation. Better anti-fouling coatings also could reduce disease transmission on Earth. Evaluating organ changes in lunar gravity Set up for the Mouse Epigenetics experiment aboard the International Space Station. NASA Researchers found different changes in gene expression and other responses to simulated lunar gravity levels in specific organs. This finding could help determine safe gravity thresholds and support development of ways to maintain skeletal and immune function on future space journeys. Spaceflight can affect skeletal and immune system function, but the molecular mechanisms of these changes are not clear. Mouse Epigenetics, a JAXA (Japan Aerospace Exploration Agency) investigation, studied gene expression changes in mice that spent a month in space and in the DNA of their offspring. Results could help determine spaceflight’s long-term effects on genetic activity, including changes within individual organs and those that can be inherited later.

The JAXA CALorimetric Electron Telescope or CALET helps address questions such as the origin and acceleration of cosmic rays and the existence of dark matter and nearby cosmic-ray sources. The instrument also could help characterize risks from the radiation environment that humans and electronics experience in space. View the full article

On March 3, 1915, the United States Congress created the National Advisory Committee for Aeronautics (NACA). Although the NACA’s founding took place just over 11 years after the Wright Brothers’ first powered flightfirst powered flight at Kitty Hawk, North Carolina, Congress took the action in response to America lagging behind other world powers’ advances in aviation and aeronautics. From its modest beginnings as an advisory committee, over the years, the NACA established research centers and test facilities that enabled groundbreaking advances in civilian and military aviation, as well as the fledgling discipline of spaceflight. With the creation of the National Aeronautics and Space Administration in 1958, the new agency incorporated the NACA’s facilities, its employees, and its annual budget. The NACA provided NASA with a strong foundation as it set out to explore space. The first meeting of the National Advisory Committee for Aeronautics on April 23, 1915.NASA The NACA executive committee in 1934. NASA The Congressional action that created the NACA, implemented as a rider to the 1915 Naval Appropriations Bill, reads in part, “…It shall be the duty of the advisory committee for aeronautics to supervise and direct the scientific study of the problems of flight with a view to their practical solution. …”. In its initial years, the NACA fulfilled its intended role, coordinating activities already in place in the area of aeronautics research, reporting directly to the president. The committee, made up of 12 representatives from government agencies, academia, and the military, first met on April 23 in the Office of the Secretary of War in Washington, D.C. It established a nine-member executive committee to oversee day-to-day operations and spent the first few years establishing its headquarters in Washington.

NASA Aerial view of the Aircraft Engine Research Laboratory in Cleveland, Ohio, in 1945.NASA Within a few years, the NACA’s role began to expand with the establishment of research facilities. The Langley Memorial Aeronautical Laboratory, today NASA’s Langley Research Center, in Hampton, Virginia, opened on June 11, 1920. Over the next few decades, Langley served as a testing facility for new types of aircraft, using wind tunnels and other technological advances. The Ames Aeronautical Laboratory in Sunnyvale, California, today NASA’s Ames Research Center, opened in 1940 and the Aircraft Engine Research Laboratory in Cleveland, today NASA’s Glenn Research Center, in 1941. The three labs achieved many breakthroughs in civilian and military aviation before, during, and after World War II. The Cleveland lab, renamed the Lewis Flight Propulsion Laboratory in 1948, concentrated most of its efforts on advances in jet propulsion.

In 1946, the agency established the Muroc Flight Test Unit at the Air Force’s Muroc Field, later renamed Edwards Air Force Base, in California’s Mojave Desert. In a close collaboration, the NACA, the Air Force, and Bell Aircraft developed the X-1 airplane that first broke the sound barrier in 1947. Muroc Field underwent several name changes, first to the High-Speed Flight Station in 1949, then in 1976 to NASA’s Dryden, and in 2014 to Armstrong Flight Research Center. In 1945, the NACA established the Pilotless Aircraft Research Station on Wallops Island, Virginia, now NASA’s Wallops Flight Facility, as a test site for rocketry research, under Langley’s direction. From the first launch in 1945 through 1958, the NACA launched nearly 400 different types of rockets from Wallops. Shadowgraph of finned hemispherical model in free flight shows shock waves produced by blunt bodies.NACA Meeting of the NACA’s Special Committee on Space Technology in May 1958.NASA In the 1950s, the NACA began to study the feasibility of spaceflight, including sending humans into space. In 1952, NACA engineers developed the concept of a blunt body capsule as the most efficient way to return humans from space. The design concept found its way into the Mercury capsule and all future American spacecraft. Following the dawn of the space age in 1957, the NACA advocated that it take the lead in America’s spaceflight effort. The Congress passed, and President Dwight D. Eisenhower signed legislation to create a new civilian space agency, and on Oct. 1, 1958, NASA officially began operations. The new organization incorporated the NACA’s research laboratories and test facilities, its 8,000 employees, and its $100 million annual budget. Many of NASA’s key early leaders and engineers began their careers in the NACA. The NACA’s last director, Hugh Dryden, served as NASA’s first deputy administrator.

On Feb. 28, 1990, space shuttle Atlantis took off from NASA’s Kennedy Space Center in Florida on STS-36, the sixth shuttle mission dedicated to the Department of Defense. As such, many of the details of the flight remain classified. The mission marked the 34th flight of the space shuttle, the sixth for Atlantis, and the fourth night launch of the program. The crew of Commander John Creighton, Pilot John Casper, Mission Specialists Mike Mullane, David Hilmers, and Pierre Thuot flew Atlantis to the highest inclination orbit of any human spaceflight to date. During the four-day mission, the astronauts deployed a classified satellite, ending with a landing at Edwards Air Force Base in California. The STS-36 crew, from left, was Mission Specialist Pierre Thuot, left, Pilot John Casper, Commander John Creighton, and Mission Specialists Mike Mullane and David Hilmers.NASA The STS-36 crew patch. NASA In February 1989, NASA assigned astronauts Creighton, Casper, Mullane, Hilmers, and Thuot to the STS-36 mission. The mission marked the second spaceflight for Creighton, selected as an astronaut in 1978. He previously served as the pilot on STS-51G. Mullane, also from the class of 1978, previously flew on STS-41D and STS-27, while Hilmers, from the class of 1980, previously flew on STS-51J and STS-26. For Casper and Thuot, selected as astronauts in the classes of 1984 and 1985, respectively, STS-36 marked their first trip into space.

The astronauts arrived on Feb. 18 for the planned launch four days later. First Creighton, then Casper and Hilmers, came down with colds, delaying the launch to Feb. 25. Weather and hardware problems pushed the launch back to Feb. 28, giving the astronauts time to return to Houston for some simulator training. On launch day, winds and rain delayed the liftoff for more than two hours before launch controllers gave Atlantis the go to launch. Liftoff of space shuttle Atlantis on STS-36. NASA With mere seconds remaining in the launch window, Atlantis lifted off at 2:50 a.m. EST Feb. 28, to begin the STS-36 mission. Atlantis flew an unusual dog leg maneuver during ascent to achieve the mission’s 62-degree inclination. Once Atlantis reached orbit, the classified nature prevented any more detailed public coverage of the mission. The astronauts likely deployed the classified satellite on the mission’s second day. During the remainder of their mission, the astronauts conducted several experiments and photographed preselected areas and targets of opportunity on planet Earth. Their high-inclination orbit enabled them to photograph areas not usually seen by shuttle crews.

On March 4, Creighton and Casper brought Atlantis to a smooth landing at Edwards Air Force Base after 72 orbits of the Earth and a flight of four days, 10 hours, and 18 minutes. About an hour after touchdown, the astronaut crew exited Atlantis for the ride to crew quarters and the flight back to Houston. Later in the day, ground crews prepared Atlantis for the ferry ride back to Kennedy. Atlantis left Edwards on March 10 and three days later arrived at Kennedy, where workers began to prepare it for its next flight, STS-38 in November 1990.

Earth (ESD) Earth Explore Explore Earth Science Climate Change Science in Action Multimedia Image Collections Videos Data For Researchers About Us 8 Min Read Going With the Flow: Visualizing Ocean Currents with ECCO The North American Gulf Stream as illustrated with the ECCO model. Credits: Greg Shirah/NASA’s Scientific Visualization Studio Historically, the ocean has been difficult to model. Scientists struggled in years past to simulate ocean currents or accurately predict fluctuations in temperature, salinity, and other properties. As a result, models of ocean dynamics rapidly diverged from reality, which meant they could only provide useful information for brief periods. In 1999, a project called Estimating the Circulation and Climate of the Ocean (ECCO) changed all that. By applying the laws of physics to data from multiple satellites and thousands of floating sensors, NASA scientists and their collaborators built ECCO to be a realistic, detailed, and continuous ocean model that spans decades. ECCO enabled thousands of scientific discoveries, and was featured during the announcement of the Nobel Prize for Physics in 2021. NASA ECCO is a powerful integrator of decades of ocean data, narrating the story of Earth’s changing ocean as it drives our weather, and sustains marine life. The ECCO project includes hundreds of millions of real-world measurements of temperature, salinity, sea ice concentration, pressure, water height, and flow in the world’s oceans. Researchers rely on the model output to study ocean dynamics and to keep tabs on conditions that are crucial for ecosystems and weather patterns. The modeling effort is supported by NASA’s Earth science programs and by the international ECCO consortium, which includes researchers from NASA’s Jet Propulsion Laboratory in Southern California and eight research institutions and universities. The project provides models that are the best possible reconstruction of the past 30 years of the global ocean. It allows us to understand the ocean’s physical processes at scales that are not normally observable. ECCO and the Western Boundary Currents Western boundary currents stand out in white in this visualization built with ECCO data. Download this visualization from NASA Goddard’s Scientific Visualization Studio. Credits: Greg Shirah/NASA’s Scientific Visualization Studio Large-scale wind patterns around the globe drag ocean surface waters with them, creating complex currents, including some that flow toward the western sides of the ocean basins. The currents hug the eastern coasts of continents as they head north or south from the equator: These are the western boundary currents. The three most prominent are the Gulf Stream, Agulhas, and Kuroshio. NASA Goddard’s Scientific Visualization Studio. The North American Gulf Stream as illustrated with the ECCO model. Download this visualization from NASA Goddard’s Scientific Visualization Studio. Credits: Greg Shirah/NASA’s Scientific Visualization Studio Seafarers have known about the Gulf Stream — the Atlantic Ocean’s western boundary current — for more than 500 years. By the volume of water it moves, the Gulf Stream is the largest of the western boundary currents, transporting more water than all the planet’s rivers combined. In 1785, Benjamin Franklin added it to maritime charts showing the current flowing up from the Gulf, along the eastern U.S. coast, and out across the North Atlantic. Franklin noted that riding the current could improve a ship’s travel time from the Americas to Europe, while avoiding the current could shorten travel times when sailing back. A visualization built of ECCO data reveals a cold, deep countercurrent that flows in the opposite direction of the warm Gulf Stream above it. Download this visualization from NASA Goddard’s Scientific Visualization Studio. Credits: Greg Shirah/NASA’s Scientific Visualization Studio Franklin’s charts showed a smooth Gulf Stream rather than the twisted, swirling path revealed in ECCO data. And Franklin couldn’t have imagined the opposing flow of water below the Gulf Stream. The countercurrent runs at depths of about 2,000 feet (600 meters) in a cold river of water that is roughly the opposite of the warm Gulf Stream at the surface. The submarine countercurrent is clearly visible when the upper layers in the ECCO model are peeled away in visualizations. The Gulf Stream is a part of the Atlantic Meridional Overturning Circulation (AMOC), which moderates climate worldwide by transporting warm surface waters north and cool underwater currents south. The Gulf Stream, in particular, stabilizes temperatures of the southeastern United States, keeping the region warmer in winter and cooler in summer than it would be without the current. After the Gulf Stream crosses the Atlantic, it tempers the climates of England and the European coast as well. The Agulhas current originates along the equator in the Indian Ocean, travels down the western coast of Africa, and spawns swirling Agulhas rings that travel across the Atlantic toward South America. Download this visualization from NASA Goddard’s Scientific Visualization Studio. Credits: Greg Shirah/NASA’s Scientific Visualization Studio The Agulhas Current flows south along the western side of the Indian Ocean. When it reaches the southern tip of Africa, it sheds swirling vortices of water called Agulhas Rings. Sometimes persisting for years, the rings glide across the Atlantic toward South America, transporting small fish, larvae, and other microorganisms from the Indian Ocean. Researchers using the ECCO model can study Agulhas Current flow as it sends warm, salty water from the tropics in the Indian Ocean toward the tip of South Africa. The model helps tease out the complicated dynamics that create the Agulhas rings and large loop of current called a supergyre that surrounds the Antarctic. The Southern Hemisphere supergyre links the southern portions of other, smaller current loops (gyres) that circulate in the southern Atlantic, Pacific, and Indian oceans. Together with gyres in the northern Atlantic and Pacific, the southern gyres and Southern Hemisphere supergyre influence climate while transporting carbon around the globe. The Kuroshio Current flows on the western side of the Pacific Ocean, past the east coast of Japan, east across the Pacific, and north toward the Arctic. Along the way, it provides warm water to drive seasonal storms, while also creating ocean upwellings that carry nutrients that sustain fisheries off the coasts of Taiwan and northern Japan. Download this visualization from NASA Goddard’s Scientific Visualization Studio. Credits: Greg Shirah/NASA’s Scientific Visualization Studio In addition to affecting global weather patterns and temperatures, western boundary currents can drive vertical flows in the oceans known as upwellings. The flows bring nutrients up from the depths to the surface, where they act as fertilizer for phytoplankton, algae, and aquatic plants. The Kuroshio Current that runs on the west side of the Pacific Ocean and along the east side of Japan has recently been associated with upwellings that enrich coastal fishing waters. The specific mechanisms that cause the vertical flows are not entirely clear. Ocean scientists are now turning to ECCO to tease out the connection between nutrient transport and currents like the Kuroshio that might be revealed in studies of the water temperature, density, pressure, and other factors included in the ECCO model. Tracking Ocean Temperatures and Salinity When viewed through the lens of ECCO’s temperature data, western boundary currents carry warm water away from the tropics and toward the poles. In the case of the Gulf Stream, as the current moves to far northern latitudes, some of the saltwater freezes into salt-free sea ice. The saltier water left behind sinks and then flows south all the way toward the Antarctic before rising and warming in other ocean basins. Colors indicate temperature in this visualization of ECCO data. Warm water near the equator is bright yellow. Water cools when it flows toward the poles, indicated by the transition to orange and red shades farther from the equator. Download this visualization from NASA Goddard’s Scientific Visualization Studio. Credits: Greg Shirah/NASA’s Scientific Visualization Studio Currents also move nutrients and salt throughout Earth’s ocean basins. Swirling vortexes of the Agulhas rings stand out in ECCO temperature and salinity maps as they move warm, salty water from the Indian Ocean into the Atlantic. The Mediterranean Sea has a dark red hue that indicates its high salt content. Other than the flow through the narrow Strait of Gibraltar, the Mediterranean is cut off from the rest of the world’s oceans. Because of this restricted flow, salinity increases in the Mediterranean as its waters warm and evaporate, making it one of the saltiest parts of the global ocean.

Credits: Greg Shirah/NASA’s Scientific Visualization Studio Experimenting with ECCO ECCO offers researchers a way to run virtual experiments that would be impractical or too costly to perform in real oceans. Some of the most important applications of the ECCO model are in ocean ecology, biology, and chemistry. Because the model shows where the water comes from and where it goes, researchers can see how currents transport heat, minerals, nutrients, and organisms around the planet. In prior decades, for example, ocean scientists relied on extensive temperature and salinity measurements by floating sensors to deduce that the Gulf Stream is primarily made of water flowing past the Gulf rather than through it. The studies were time-consuming and expensive. With the ECCO model, data visualizers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, virtually replicated the research in a simulation that was far quicker and cheaper. A simulation built with data from the ECCO model shows that very little of the water in the gulf contributes to the water flowing in the Gulf Stream. Download this visualization from NASA Goddard’s Scientific Visualization Studio. Credits: Atousa Saberi/NASA’s Scientific Visualization Studio The example illustrated here relies on ECCO to track the flow of water by virtually filling the Gulf with 115,000 particles and letting them move for a year in the model. The demonstration showed that less than 1% of the particles escape the Gulf to join the Gulf Stream. Running such particle-tracking experiments within the ocean circulation models helps scientists understand how and where environmental contaminants, such as oil spills, can spread. Take an ECCO Deep Dive Today, researchers turn to ECCO for a broad array of studies. They can choose ECCO modeling products that focus on one feature – such as global flows or the biology and chemistry of the ocean – or they can narrow the view to the poles or specific ocean regions. Every year, more than a hundred scientific papers include data and analyses from the ECCO model that delve into our oceans’ properties and dynamics.

Credits: NASA, ESA, CSA, and Joseph Olmsted (STScI) An international team of researchers has discovered that previously observed variations in brightness of a free-floating planetary-mass object known as SIMP 0136 must be the result of a complex combination of atmospheric factors, and cannot be explained by clouds alone. Using NASA’s James Webb Space Telescope to monitor a broad spectrum of infrared light emitted over two full rotation periods by SIMP 0136, the team was able to detect variations in cloud layers, temperature, and carbon chemistry that were previously hidden from view. The results provide crucial insight into the three-dimensional complexity of gas giant atmospheres within and beyond our solar system. Detailed characterization of objects like these is essential preparation for direct imaging of exoplanets, planets outside our solar system, with NASA’s Nancy Grace Roman Space Telescope, which is scheduled to begin operations in 2027. Rapidly Rotating, Free-Floating SIMP 0136 is a rapidly rotating, free-floating object roughly 13 times the mass of Jupiter, located in the Milky Way just 20 light-years from Earth. Although it is not classified as a gas giant exoplanet — it doesn’t orbit a star and may instead be a brown dwarf — SIMP 0136 is an ideal target for exo-meteorology: It is the brightest object of its kind in the northern sky. Because it is isolated, it can be observed with no fear of light contamination or variability caused by a host star. And its short rotation period of just 2.4 hours makes it possible to survey very efficiently. Prior to the Webb observations, SIMP 0136 had been studied extensively using ground-based observatories and NASA’s Hubble and Spitzer space telescopes. “We already knew that it varies in brightness, and we were confident that there are patchy cloud layers that rotate in and out of view and evolve over time,” explained Allison McCarthy, doctoral student at Boston University and lead author on a study published today in The Astrophysical Journal Letters. “We also thought there could be temperature variations, chemical reactions, and possibly some effects of auroral activity affecting the brightness, but we weren’t sure.” To figure it out, the team needed Webb’s ability to measure very precise changes in brightness over a broad range of wavelengths. Graphic A: Isolated Planetary-Mass Object SIMP 0136 (Artist’s Concept) This artist’s concept shows what the isolated planetary-mass object SIMP 0136 could look like based on recent observations from NASA’s James Webb Space Telescope and previous observations from Hubble, Spitzer, and numerous ground-based telescopes. Researchers used Webb’s NIRSpec (Near-Infrared Spectrograph) and MIRI (Mid-Infrared Instrument) to measure subtle changes in the brightness of infrared light as the object completed two 2.4-hour rotations. By analyzing the change in brightness of different wavelengths over time, they were able to detect variability in cloud cover at different depths, temperature variations in the upper atmosphere, and changes in carbon chemistry as different sides of the object rotated in and out of view. This illustration is based on Webb’s spectroscopic observations. Webb has not captured a direct image of the object. NASA, ESA, CSA, and Joseph Olmsted (STScI) Charting Thousands of Infrared Rainbows Using NIRSpec (Near-Infrared Spectrograph), Webb captured thousands of individual 0.6- to 5.3-micron spectra — one every 1.8 seconds over more than three hours as the object completed one full rotation. This was immediately followed by an observation with MIRI (Mid-Infrared Instrument), which collected hundreds of spectroscopic measurements of 5- to 14-micron light — one every 19.2 seconds, over another rotation. The result was hundreds of detailed light curves, each showing the change in brightness of a very precise wavelength (color) as different sides of the object rotated into view. “To see the full spectrum of this object change over the course of minutes was incredible,” said principal investigator Johanna Vos, from Trinity College Dublin. “Until now, we only had a little slice of the near-infrared spectrum from Hubble, and a few brightness measurements from Spitzer.” The team noticed almost immediately that there were several distinct light-curve shapes. At any given time, some wavelengths were growing brighter, while others were becoming dimmer or not changing much at all. A number of different factors must be affecting the brightness variations. “Imagine watching Earth from far away. If you were to look at each color separately, you would see different patterns that tell you something about its surface and atmosphere, even if you couldn’t make out the individual features,” explained co-author Philip Muirhead, also from Boston University. “Blue would increase as oceans rotate into view. Changes in brown and green would tell you something about soil and vegetation.” Graphic B: Isolated Planetary-Mass Object SIMP 0136 (NIRSpec Light Curves) These light curves show the change in brightness of three different sets of wavelengths (colors) of near-infrared light coming from the isolated planetary-mass object SIMP 0136 as it rotated. The light was captured by Webb’s NIRSpec (Near-Infrared Spectrograph), which collected a total of 5,726 spectra — one every 1.8 seconds — over the course of about 3 hours on July 23, 2023. The variations in brightness are thought to be related to different atmospheric features — deep clouds composed of iron particles, higher clouds made of tiny grains of silicate minerals, and high-altitude hot and cold spots — rotating in and out of view. The diagram at the right illustrates the possible structure of SIMP 0136’s atmosphere, with the colored arrows representing the same wavelengths of light shown in the light curves. Thick arrows represent more (brighter) light; thin arrows represent less (dimmer) light. NASA, ESA, CSA, and Joseph Olmsted (STScI) Patchy Clouds, Hot Spots, and Carbon Chemistry To figure out what could be causing the variability on SIMP 0136, the team used atmospheric models to show where in the atmosphere each wavelength of light was originating. “Different wavelengths provide information about different depths in the atmosphere,” explained McCarthy. “We started to realize that the wavelengths that had the most similar light-curve shapes also probed the same depths, which reinforced this idea that they must be caused by the same mechanism.” One group of wavelengths, for example, originates deep in the atmosphere where there could be patchy clouds made of iron particles. A second group comes from higher clouds thought to be made of tiny grains of silicate minerals. The variations in both of these light curves are related to patchiness of the cloud layers. A third group of wavelengths originates at very high altitude, far above the clouds, and seems to track temperature. Bright “hot spots” could be related to auroras that were previously detected at radio wavelengths, or to upwelling of hot gas from deeper in the atmosphere. Some of the light curves cannot be explained by either clouds or temperature, but instead show variations related to atmospheric carbon chemistry. There could be pockets of carbon monoxide and carbon dioxide rotating in and out of view, or chemical reactions causing the atmosphere to change over time. “We haven’t really figured out the chemistry part of the puzzle yet,” said Vos. “But these results are really exciting because they are showing us that the abundances of molecules like methane and carbon dioxide could change from place to place and over time. If we are looking at an exoplanet and can get only one measurement, we need to consider that it might not be representative of the entire planet.” This research was conducted as part of Webb’s General Observer Program 3548. The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) To celebrate the 110th anniversary of the organization that ultimately became NASA, the agency released a new collection of videos to highlight the history of the National Advisory Committee for Aeronautics (NACA) and the ways it transformed flight over four decades. A new video collection highlights the history and significance of NASA’s predecessor organization. Not long after the beginning of World War I, the United States Congress, concerned that America was lagging behind other countries, created a new committee to advance the nation’s flight technology development. On March 3, 1915, the NACA was founded “to supervise and direct the scientific study of the problems of flight, with a view to their practical solution.” While the NACA began as a committee of only 12 leaders representing government, military, and industry, it rapidly expanded through World War II to develop America’s flight capabilities for defense and commercial uses. The organization became home to some of the nation’s best and brightest aeronautical engineers and world-class facilities, transforming into NASA at the dawn of the Space Age in 1958. The new video collection highlights some of NACA’s striking historic photography and celebrates this pioneering organization with a brief history of its formation, expansion, and groundbreaking aeronautics research at four centers across the United States — the current homes of NASA’s Langley Research Center in Hampton Virginia, Ames Research Center in California’s Silicon Valley, Glenn Research Center in Cleveland, and Armstrong Flight Research Center in Edwards, California.

First image captured by Firefly’s Blue Ghost lunar lander, taken shortly after confirmation of a successful landing at Mare Crisium on the Moon’s near side. This is the second lunar delivery of NASA science and tech instruments as part of the agency’s Commercial Lunar Payload Services initiative.Credit: Firefly Aerospace Carrying a suite of NASA science and technology, Firefly Aerospace’s Blue Ghost Mission 1 successfully landed at 3:34 a.m. EST on Sunday near a volcanic feature called Mons Latreille within Mare Crisium, a more than 300-mile-wide basin located in the northeast quadrant of the Moon’s near side. The Blue Ghost lander is in an upright and stable configuration, and the successful Moon delivery is part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign. This is the first CLPS delivery for Firefly, and their first Moon landing. The 10 NASA science and technology instruments aboard the lander will operate on the lunar surface for approximately one lunar day, or about 14 Earth days. “This incredible achievement demonstrates how NASA and American companies are leading the way in space exploration for the benefit of all,” said NASA acting Administrator Janet Petro. “We have already learned many lessons – and the technological and science demonstrations onboard Firefly’s Blue Ghost Mission 1 will improve our ability to not only discover more science, but to ensure the safety of our spacecraft instruments for future human exploration – both in the short term and long term.” Since launching from NASA’s Kennedy Space Center in Florida on Jan. 15, Blue Ghost traveled more than 2.8 million miles, downlinked more than 27 GB of data, and supported several science operations. This included signal tracking from the Global Navigation Satellite System (GNSS) at a record-breaking distance of 246,000 miles with the Lunar GNSS Receiver Experiment payload – showing NASA can use the same positioning systems on Earth when at the Moon. Science conducted during the journey also included radiation tolerant computing through the Van Allen Belts with the Radiation-Tolerant Computer System payload and measurements of magnetic field changes in space with the Lunar Magnetotelluric Sounder payload. “The science and technology we send to the Moon now helps prepare the way for future NASA exploration and long-term human presence to inspire the world for generations to come,” said Nicky Fox, associate administrator for science at NASA Headquarters in Washington. “We’re sending these payloads by working with American companies – which supports a growing lunar economy.” During surface operations, the NASA instruments will test and demonstrate lunar subsurface drilling technology, regolith sample collection capabilities, global navigation satellite system abilities, radiation tolerant computing, and lunar dust mitigation methods. The data captured will benefit humanity by providing insights into how space weather and other cosmic forces impact Earth. Before payload operations conclude, teams will aim to capture imagery of the lunar sunset and how lunar dust reacts to solar influences during lunar dusk conditions, a phenomenon first documented by former NASA astronaut Eugene Cernan on Apollo 17. Following the lunar sunset, the lander will operate for several hours into the lunar night. “On behalf of our entire team, I want to thank NASA for entrusting Firefly as their lunar delivery provider,” said Jason Kim, CEO of Firefly Aerospace. “Blue Ghost’s successful Moon landing has laid the groundwork for the future of commercial exploration across cislunar space. We’re now looking forward to more than 14 days of surface operations to unlock even more science data that will have a substantial impact on future missions to the Moon and Mars.” To date, five vendors have been awarded 11 lunar deliveries under CLPS and are sending more than 50 instruments to various locations on the Moon, including the lunar South Pole. Existing CLPS contracts are indefinite-delivery, indefinite-quantity contracts with a cumulative maximum contract value of $2.6 billion through 2028.

The view is looking down at a flattened pile of tailings created by the coring of science target “Green Gardens,” so named because it contains serpentine, a mineral often green in color. The rover’s SHERLOC instrument (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals) uses cameras, spectrometers, and a laser to search for organics and minerals that have been altered by watery environments and may be signs of past microbial life; in addition to its black-and-white context camera, SHERLOC is assisted by WATSON (Wide Angle Topographic Sensor for Operations and eNgineering), a color camera for taking close-up images of rock grains and surface textures. Perseverance acquired this image on Feb. 20, 2025 — sol 1424, or Martian day 1,424 of the Mars 2020 mission — at the local mean solar time of 13:11:41. This photo was selected by public vote and featured as “Image of the Week” for Week 210 (Feb. 16-22, 2025) of the Perseverance rover mission on Mars. NASA/JPL-Caltech Written by Henry Manelski, Ph.D. student at Purdue University The Perseverance team is always looking for creative ways to use the tools we have on Mars to maximize the science we do. On the arm of the rover sits the SHERLOC instrument, which specializes in detecting organic compounds and is crucial in our search for signs of past microbial life. But finding these organics isn’t easy. The uppermost surface of most rocks Perseverance finds on Mars have been exposed to ultraviolet rays from the sun and the long-term oxidative potential of the atmosphere, both of which have the potential to break down organic compounds. For this reason, obtaining SHERLOC measurements from a “fresh” rock face is ideal. Last week the rover cored a serpentine-rich rock aptly named “Green Gardens,” resulting in a fresh pile of drill tailings. To get this material ready for the SHERLOC instrument, which requires a smooth area to obtain a measurement, the science team did something for the first time on Mars: We smooshed it! Using the contact sensor of our sampling system, designed to indicate when our drill is touching a rock as it prepares to take a core, Perseverance pressed down into the tailings pile, compacting it into a flat, stable patch for SHERLOC to investigate. This unorthodox approach worked perfectly! The resulting SHERLOC spectral scan of these fresh tailings — which include serpentine, a mineral of key astrobiological interest — was a success. These flattened drill tailings are a great example of how a bit of out-of-the-box (or out-of-this-world!) thinking helps us maximize science on Mars. With this success behind us, the rover is rolling west toward the heart of “Witch Hazel Hill,” where more ancient rocks — and who knows what surprises — await!

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The Compact Fire Infrared Radiance Spectral tracker, or C-FIRST, is managed an operated by NASA’s Jet Propulsion Laboratory, and supported by NASA’s Earth Science Technology Office. Combining state-of-the-art imaging technology with a compact design, C-FIRST enables scientists to gather data about fires and their impacts on ecosystems with greater accuracy and speed than other instruments. C-FIRST was developed as a spaceborne instrument, and flew onboard NASA’s B200 aircraft in January 2025 to conduct an airborne test.NASA/JPL-Caltech The January wildfires in California devastated local habitats and communities. In an effort to better understand wildfire behavior, NASA scientists and engineers tried to learn from the events by testing new technology. The new instrument, the Compact Fire Infrared Radiance Spectral Tracker (c-FIRST), was tested when NASA’s B200 King Air aircraft flew over the wildfires in the Pacific Palisades and Altadena, California. Based at NASA’s Armstrong Flight Research Center in Edwards, California, the aircraft used the c-FIRST instrument to observe the impacts of the fires in near real-time. Due to its small size and ability to efficiently simulate a satellite-based mission, the B200 King Air is uniquely suited for testing c-FIRST. Managed and operated by NASA’s Jet Propulsion Laboratory in Southern California, c-FIRST gathers thermal infrared images in high-resolution and other data about the terrain to study the impacts of wildfires on ecology. In a single observation, c-FIRST can capture the full temperature range across a wide area of wildland fires – as well as the cool, unburned background – potentially increasing both the quantity and quality of science data produced. “Currently, no instrument is able to cover the entire range of attributes for fires present in the Earth system,” said Sarath Gunapala, principal investigator for c-FIRST at NASA JPL. “This leads to gaps in our understanding of how many fires occur, and of crucial characteristics like size and temperature.” For decades, the quality of infrared images has struggled to convey the nuances of high-temperature surfaces above 1,000 degrees Fahrenheit (550 degrees Celsius). Blurry resolution and light saturation of infrared images has inhibited scientists’ understanding of an extremely hot terrain, and thereby also inhibited wildfire research. Historically, images of extremely hot targets often lacked the detail scientists need to understand the range of a fire’s impacts on an ecosystem. NASA’s Armstrong Flight Research Center in Edwards, California, flew the B200 King Air in support of the Signals of Opportunity Synthetic Aperture Radar (SoOpSAR) campaign on Feb. 27, 2023.NASA/Steve Freeman To address this, NASA’s Earth Science Technology Office supported JPL’s development of the c-FIRST instrument, combining state-of-the-art imaging technology with a compact and efficient design. When c-FIRST was airborne, scientists could detect smoldering fires more accurately and quickly, while also gathering important information on active fires in near real-time. “These smoldering fires can flame up if the wind picks up again,” said Gunapala. “Therefore, the c-FIRST data set could provide very important information for firefighting agencies to fight fires more effectively.” For instance, c-FIRST data can help scientists estimate the likelihood of a fire spreading in a certain landscape, allowing officials to more effectively monitor smoldering fires and track how fires evolve. Furthermore, c-FIRST can collect detailed data that can enable scientists to understand how an ecosystem may recover from fire events. “The requirements of the c-FIRST instrument meet the flight profile of the King Air,” said KC Sujan, operations engineer for the B200 King Air. “The c-FIRST team wanted a quick integration, the flight speed in the range 130 and 140 knots on a level flight, communication and navigation systems, and the instruments power requirement that are perfectly fit for King Air’s capability.” By first testing the instrument onboard the B200 King Air, the c-FIRST team can evaluate its readiness for future satellite missions investigating wildfires. On a changing planet where wildfires are increasingly common, instruments like c-FIRST could provide data that can aid firefighting agencies to fight fires more effectively, and to understand the ecosystemic impacts of extreme weather events.

Skywatching Science Skywatching What’s Up: March 2025… Skywatching Home What’s Up What to See Tonight Moon Guide Eclipses Meteor Showers More Tips & Guides Skywatching FAQ A Fast-Moving Planet and a Crimson Moon! Catch Mercury if you can, then stay up late for a total lunar eclipse, and learn the truth about the dark side of the Moon. Skywatching Highlights All Month – Planets Visibility: Mercury: Speedy Mercury is visible beneath Venus for the first week and a half of March, for about 30 minutes each evening, as sunset fades. Venus: Venus hangs low in the west after sunset early in the month, but quickly drops lower as the days pass. After mid-March, it’s difficult to observe in the glow of fading sunlight. Mars: Find Mars high in the east following sunset, then setting around 3 a.m. Jupiter: Visible high in the west after dark, and setting about 1 a.m. Daily Highlights: March 7-9 – Catch Mercury: Look for Mercury beginning about 30 minutes after sunset in the west, about 10 degrees above the horizon. March 13-14 – Total Lunar Eclipse: The Moon becomes a crimson orb over a couple of hours on March 13th and into the 14th, depending on your time zone. March 14 – Full moon March 29 – New moon: This is when the dark side of the Moon faces toward Earth. The new moon appears close to the Sun in the sky, so it’s essentially invisible from the surface (except during solar eclipses). Transcript What’s Up for March? A good time to catch Mercury, an eclipse approaches, and the dark side of the Moon. March Planet Viewing March begins with Venus still hanging out low in the west after sunset, but it quickly drops out of the sky – by mid-month it’s getting lost in the glare of sunset. Once it gets dark, you’ll find Jupiter and Mars high overhead, keeping you company through the evening. Mars sets a couple of hours after midnight this month, leaving the morning sky “planet free” for the first time in a year. Sky chart showing Venus and Mercury after sunset in early March. NASA/JPL-Caltech March also has the best opportunity this year for trying to spot fast-moving Mercury if you’re in the Northern Hemisphere. It’s only visible for a few weeks at a time every 3 to 4 months. This is because the speedy planet orbits the Sun in just 88 days, so it quickly shifts its position in the sky from day to day. It’s always visible either just after sunset or just before sunrise. On March 7th through 9th, look for Mercury beginning about 30 minutes after sunset in the west, about 10 degrees above the horizon. You’ll want to ensure your view isn’t blocked by trees, buildings, or other obstructions. Observing from a large, open field, or the shore of a lake or the seaside can be helpful. Spying Mercury isn’t always easy, but catching the fleet-footed planet is a worthy goal for any skywatcher. Total Lunar Eclipse This map shows where the Moon will be above the horizon during the March 13-14 total lunar eclipse. There’s a total lunar eclipse on the way this month, visible across the Americas. Lunar eclipses can be viewed from anywhere the Moon is above the horizon at the time. The show unfolds overnight on March 13th and into the 14th, depending on your time zone. Check the schedule for your area for precise timing. Now, during a total lunar eclipse, we watch as the Moon passes through Earth’s shadow. It first appears to have a bite taken out of one side, but as maximum eclipse nears, the Moon transforms into a deep crimson orb. That red color comes from the ring of all the sunsets and sunrises you’d see encircling our planet if you were an astronaut on the lunar surface right then. Afterward, the eclipse plays out in reverse, with the red color fading, and the dark bite shrinking, until the Moon looks like its usual self again. And here’s an interesting pattern: eclipses always arrive in pairs. A couple weeks before or after a total lunar eclipse, there’s always a solar eclipse. This time, it’s a partial solar eclipse that will be visible across Eastern Canada, Greenland, and Northern Europe. The Dark Side of the Moon The Moon has a dark side, but it may not be what you think. As it orbits around Earth each month, the Moon is also rotating (or spinning). So, while we always see the same face of the Moon, sunlight sweeps across the lunar surface every month as it rotates. This means there’s no permanently “dark” side. The Moon’s dark side faces Earth when the Moon passes between our planet and the Sun each month. This is the moment when the Moon is said to be “new,” as in a fresh start for its changing phases. The new moon is also located quite close the Sun in the sky, making it more or less invisible, unless there’s a solar eclipse. Nights around the new moon phase provide excellent opportunities for observing the sky – especially if you’re using a telescope or doing astrophotography. Without moonlight washing out the sky, you can better see faint stars, nebulas, the Milky Way, and distant galaxies. So next time someone mentions the “dark side of the Moon,” you’ll know there’s more to the story – and you might even discover some deep-sky treasures while the Moon takes its monthly break. The phases of the Moon for March 2025. NASA/JPL-Caltech Above are the phases of the Moon for March. Stay up to date on all of NASA’s missions exploring the solar system and beyond at NASA Science.

ESA/Hubble & NASA, R. Sankrit Download this image In this NASA/ESA Hubble Space Telescope image, Hubble once again lifts the veil on a famous — and frequently photographed — supernova remnant: the Veil Nebula. The remnant of a star roughly 20 times as massive as the Sun that exploded about 10,000 years ago, the Veil Nebula is situated about 2,400 light-years away in the constellation Cygnus. Hubble images of this photogenic nebula were first taken in 1994 and 1997, and again in 2015. This view combines images taken in three different filters by Hubble’s Wide Field Camera 3, highlighting emission from hydrogen, sulfur, and oxygen atoms. The image shows just a small fraction of the Veil Nebula; if you could see the entire nebula without the aid of a telescope, it would be as wide as six full Moons placed side-by-side. Although this image captures the Veil Nebula at a single point in time, it helps researchers understand how the supernova remnant evolves over decades. Combining this snapshot with Hubble observations from 1994 will reveal the motion of individual knots and filaments of gas over that span of time, enhancing our understanding of this stunning nebula.

Project Manager – Goddard Space Flight Center Growing up near Dover Air Force Base in Delaware, Jamie Dunn — now a project manager for NASA’s Nancy Grace Roman Space Telescope — naturally became interested in planes. While he initially wanted to be a pilot, he chose aerospace engineering as a college major. “I originally had no plans to work in the space industry,” Jamie recalls. “I never imagined I’d be working at NASA.” While pursuing his degree at the University of Maryland, he heard about a cooperative education program at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. He applied, was accepted, and has been at Goddard ever since. Jamie Dunn serves as a project manager for NASA’s Nancy Grace Roman Space Telescope. The observatory is currently taking shape in the largest clean room at the agency’s Goddard Space Flight Center in Greenbelt, Md., seen behind Jamie in this photo.NASA/Chris Gunn “I started out as a thermal vacuum test engineer, first focusing on smaller stuff and then I worked my way up to doing more complicated tests,” he says. “Before getting into the co-op program, I didn’t even know that job existed.” Jamie worked at Goddard mostly part-time while going to school and the role transitioned to a full-time job upon graduation. He continued working as a test engineer for several years and then became his group’s section head — his first supervisory role. From there, Jamie became the integration and testing manager for the Wide Field Camera 3, which was flown on Hubble Space Telescope Servicing Mission 4. That role teed him up for subsequent positions with the James Webb Space Telescope’s ISIM (Integrated Science Instrument Module) — first as the integration and testing manager, then deputy project manager, and ultimately the manager. Jamie Dunn, pictured at left, gives a tour to Nicola Fox (center), the associate administrator for science, and Wanda Peters (at right), the associate administrator for programs.NASA/Jolearra Tshiteya “The thirteen years I was on ISIM were like thirty,” Jamie says. “It was a very complex role involving international partnerships, contractors, and in-house personnel. We overcame a lot of adversity over the years in completing our work, and I learned a tremendous amount to be applied to my career going forward.” Following his time with Webb, Jamie spent a couple of years working on GOES-R (the Geostationary Operational Environmental Satellites–R Series), initially as deputy project manager and then project manager. “The biggest change was that GOES is out-of-house, so none of the hardware was developed at Goddard,” Jamie says. “That’s a huge difference.” In 2018, Jamie joined the Roman team in his current position of project manager. “In project management, you’re there to keep the train on the tracks and get to the station on time,” he says. “I focus heavily on programmatics, working closely with mission systems and project science, whose primary focus is on technical performance and science return. And when you have a healthy balance between them all like we do, it turns out to be a very successful endeavor.” A couple of years into the role, the COVID-19 pandemic struck. “It’s hard to put a spacecraft together when you’re not allowed to come to work,” Jamie says. “It was difficult because no one had experienced anything like it before, so everyone was trying to figure it out as we went along. We really focused on the team dynamic, being mindful of personal circumstances while aggressively pushing to resume onsite.” Now, the Roman mission is within a couple years of launch. Jamie’s looking forward to seeing all the engineering work translate into mind-boggling images of space. Roman will usher in a new era of cosmic surveys, discovering billions of cosmic objects at a rate never before seen in astrophysics. “When we launch this thing, that’ll definitely be the highlight of my career,” he says. “It’s really an honor to work with such a brilliant and dedicated team. For much of his time at NASA, Jamie has balanced running a project with running a household, taking care of three sons with his wife. “There’s a surprising amount of overlap between the two, because at the end of the day, it all comes down to people,” he says. “A lot of the job is psychological; having good working relationships across the team is crucial for success. To others who are interested in pursuing a similar career, Jamie recommends avoiding the “rush to the top.” He says, “I think it’s very important to make sure you spend time along the way to learn your craft. There’s no substitute for experience, and there are a lot of people to listen to and learn from along the way. Then you’ll be better prepared when you do land the job you’re ultimately aiming for.” By Ashley Balzer NASA’s Goddard Space Flight Center View the full article

NASA/Brandon Torres Navarrete Engineers at NASA’s Ames Research Center in California’s Silicon Valley, Bohdan Wesely, right, and Eli Hiss, left, complete a fit check of the two halves of a space capsule that will study the clouds of Venus for signs of life. Led by Rocket Lab of Long Beach, California, and their partners at the Massachusetts Institute of Technology in Cambridge, Rocket Lab’s Venus mission will be the first private mission to the planet. NASA’s role is to help the commercial space endeavor succeed by providing expertise in thermal protection of small spacecraft. Invented at Ames, NASA’s Heatshield for Extreme Entry Environment Technology (HEEET) – the brown, textured material covering the bottom of the capsule in this photo – is a woven heat shield designed to protect spacecraft from temperatures up to 4,500 degrees Fahrenheit. The probe will deploy from Rocket Lab’s Photon spacecraft bus, taking measurements as it descends through the planet’s atmosphere. Teams at Ames work with private companies, like Rocket Lab, to turn NASA materials into solutions such as the heat shield tailor-made for this spacecraft destined for Venus, supporting growth of the new space economy. NASA’s Small Spacecraft Technology program, part of the agency’s Space Technology Mission Directorate, supported development of the heat shield for Rocket Lab’s Venus mission. View the full article

Credits: NASA, ESA, Alessandro Savino (UC Berkeley), Joseph DePasquale (STScI), Akira Fujii DSS2 Located 2.5 million light-years away, the majestic Andromeda galaxy appears to the naked eye as a faint, spindle-shaped object roughly the angular size of the full Moon. What backyard observers don’t see is a swarm of nearly three dozen small satellite galaxies circling the Andromeda galaxy, like bees around a hive. These satellite galaxies represent a rambunctious galactic “ecosystem” that NASA’s Hubble Space Telescope is studying in unprecedented detail. This ambitious Hubble Treasury Program used observations from more than a whopping 1,000 Hubble orbits. Hubble’s optical stability, clarity, and efficiency made this ambitious survey possible. This work included building a precise 3D mapping of all the dwarf galaxies buzzing around Andromeda and reconstructing how efficiently they formed new stars over the nearly 14 billion years of the universe’s lifetime. This is a wide-angle view of the distribution of known satellite galaxies orbiting the large Andromeda galaxy (M31), located 2.5 million light-years away. The Hubble Space Telescope was used to study the entire population of 36 mini-galaxies circled in yellow. Andromeda is the bright spindle-shaped object at image center. All the dwarf galaxies seem to be confined to a plane, all orbiting in the same direction. The wide view is from ground-based photography. Hubble’s optical stability, clarity, and efficiency made this ambitious survey possible. Hubble close up snapshots of four dwarf galaxies are on image right. The most prominent dwarf galaxy is M32 (NGC 221), a compact ellipsoidal galaxy that might be the remnant core of a larger galaxy that collided with Andromeda a few billion years ago. NASA, ESA, Alessandro Savino (UC Berkeley), Joseph DePasquale (STScI), Akira Fujii DSS2 In the study published in The Astrophysical Journal, Hubble reveals a markedly different ecosystem from the smaller number of satellite galaxies that circle our Milky Way. This offers forensic clues as to how our Milky Way galaxy and Andromeda have evolved differently over billions of years. Our Milky Way has been relatively placid. But it looks like Andromeda has had a more dynamic history, which was probably affected by a major merger with another big galaxy a few billion years ago. This encounter, and the fact that Andromeda is as much as twice as massive as our Milky Way, could explain its plentiful and diverse dwarf galaxy population. Surveying the Milky Way’s entire satellite system in such a comprehensive way is very challenging because we are embedded inside our galaxy. Nor can it be accomplished for other large galaxies because they are too far away to study the small satellite galaxies in much detail. The nearest galaxy of comparable mass to the Milky Way beyond Andromeda is M81, at nearly 12 million light-years. This bird’s-eye view of Andromeda’s satellite system allows us to decipher what drives the evolution of these small galaxies. “We see that the duration for which the satellites can continue forming new stars really depends on how massive they are and on how close they are to the Andromeda galaxy,” said lead author Alessandro Savino of the University of California at Berkeley. “It is a clear indication of how small-galaxy growth is disturbed by the influence of a massive galaxy like Andromeda.” “Everything scattered in the Andromeda system is very asymmetric and perturbed. It does appear that something significant happened not too long ago,” said principal investigator Daniel Weisz of the University of California at Berkeley. “There’s always a tendency to use what we understand in our own galaxy to extrapolate more generally to the other galaxies in the universe. There’s always been concerns about whether what we are learning in the Milky Way applies more broadly to other galaxies. Or is there more diversity among external galaxies? Do they have similar properties? Our work has shown that low-mass galaxies in other ecosystems have followed different evolutionary paths than what we know from the Milky Way satellite galaxies.” For example, half of the Andromeda satellite galaxies all seem to be confined to a plane, all orbiting in the same direction. “That’s weird. It was actually a total surprise to find the satellites in that configuration and we still don’t fully understand why they appear that way,” said Weisz.

We zoom through a scattering of foreground stars and enter the inky blackness of intergalactic space. We cross 2.5 million light-years to reach the Andromeda system, consisting of 36 dwarf satellite galaxies orbiting the giant spindle-shaped Andromeda galaxy at image center. An ambitious survey by the Hubble Space Telescope was made to plot the galaxy locations in three-dimensional space. In this video we circle around a model of the Andromeda system based on real Hubble observational data. NASA, ESA, Christian Nieves (STScI), Alessandro Savino (UC Berkeley); Acknowledgment: Joseph DePasquale (STScI), Frank Summers (STScI), Robert Gendler The brightest companion galaxy to Andromeda is Messier 32 (M32). This is a compact ellipsoidal galaxy that might just be the remnant core of a larger galaxy that collided with Andromeda a few billion years ago. After being gravitationally stripped of gas and some stars, it continued along its orbit. Galaxy M32 contains older stars, but there is evidence it had a flurry of star formation a few billion years ago. In addition to M32, there seems to be a unique population of dwarf galaxies in Andromeda not seen in the Milky Way. They formed most of their stars very early on, but then they didn’t stop. They kept forming stars out of a reservoir of gas at a very low rate for a much longer time. “Star formation really continued to much later times, which is not at all what you would expect for these dwarf galaxies,” continued Savino. “This doesn’t appear in computer simulations. No one knows what to make of that so far.” “We do find that there is a lot of diversity that needs to be explained in the Andromeda satellite system,” added Weisz. “The way things come together matters a lot in understanding this galaxy’s history.” Hubble is providing the first set of imaging where astronomers measure the motions of the dwarf galaxies. In another five years Hubble or NASA’s James Webb Space Telescope will be able to get the second set of observations, allowing astronomers to do a dynamical reconstruction for all 36 of the dwarf galaxies, which will help astronomers to rewind the motions of the entire Andromeda ecosystem billions of years into the past. The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.
