Hubble Captures Young Stars Changing Their Environments
This NASA/ESA Hubble Space Telescope image features the nearest star-forming region to Earth, the Orion Nebula (Messier 42, M42), located some 1,500 light-years away. ESA/Hubble, NASA, and T. Megeath This NASA/ESA Hubble Space Telescope image peers into the dusty recesses of the nearest massive star-forming region to Earth, the Orion Nebula (Messier 42, M42). Just 1,500 light-years away, the Orion Nebula is visible to the unaided eye below the three stars that form the ‘belt’ in the constellation Orion. The nebula is home to hundreds of newborn stars including the subject of this image: the protostars HOPS 150 and HOPS 153.
These protostars get their names from the Herschel Orion Protostar Survey, conducted with ESA’s Herschel Space Observatory. The object visible in the upper-right corner of this image is HOPS 150: it’s a binary star system where two young protostars orbit each other. Each star has a small, dusty disk of material surrounding it. These stars gather material from their respective dust disks, growing in the process. The dark line that cuts across the bright glow of these protostars is a cloud of gas and dust falling in on the pair of protostars. It is over 2,000 times wider than the distance between Earth and the Sun. Based on the amount of infrared light HOPS 150 is emitting, as compared to other wavelengths it emits, the protostars are mid-way down the path to becoming mature stars.
Extending across the left side of the image is a narrow, colorful outflow called a jet. This jet comes from the nearby protostar HOPS 153, which is out of the frame. HOPS 153 is significantly younger than its neighbor. That stellar object is still deeply embedded in its birth nebula and enshrouded by a cloud of cold, dense gas. While Hubble cannot penetrate this gas to see the protostar, the jet HOPS 153 emitted is brightly and clearly visible as it plows into the surrounding gas and dust of the Orion Nebula.
The transition from tightly swaddled protostar to fully fledged star will dramatically affect HOPS 153’s surroundings. As gas falls onto the protostar, its jets spew material and energy into interstellar space, carving out bubbles and heating the gas. By stirring up and warming nearby gas, HOPS 153 may regulate the formation of new stars in its neighborhood and even slow its own growth.

Astronomers have released a set of more than a million simulated images showcasing the cosmos as NASA’s upcoming Nancy Grace Roman Space Telescope will see it. This preview will help scientists explore a myriad of Roman’s science goals.
“We used a supercomputer to create a synthetic universe and simulated billions of years of evolution, tracing every photon’s path all the way from each cosmic object to Roman’s detectors,” said Michael Troxel, an associate professor of physics at Duke University in Durham, North Carolina, who led the simulation campaign. “This is the largest, deepest, most realistic synthetic survey of a mock universe available today.”

This video begins with a tiny one-square-degree portion of the full OpenUniverse simulation area (about 70 square degrees, equivalent to an area of sky covered by more than 300 full moons). It spirals in toward a particularly galaxy-dense region, zooming by a factor of 75. This simulation showcases the cosmos as NASA’s Nancy Grace Roman Space Telescope could see it, allowing scientists to preview the next generation of cosmic discovery now. Roman’s real future surveys will enable a deep dive into the universe with highly resolved imaging, as demonstrated in this video. NASA’s Goddard Space Flight Center and M. Troxel The project, called OpenUniverse, relied on the now-retired Theta supercomputer at the DOE’s (Department of Energy’s) Argonne National Laboratory in Illinois. The supercomputer accomplished a process that would take over 6,000 years on a typical computer in just nine days.
In addition to Roman, the 400-terabyte dataset will also preview observations from the Vera C. Rubin Observatory, which is jointly funded by the National Science Foundation and the U.S. Department of Energy, and approximate simulations from ESA’s (the European Space Agency’s) Euclid mission, which has NASA contributions. The Roman data is available now here, and the Rubin and Euclid data will soon follow.
The team used the most sophisticated modeling of the universe’s underlying physics available and fed in information from existing galaxy catalogs and the performance of the telescopes’ instruments. The resulting simulated images span 70 square degrees, equivalent to an area of sky covered by more than 300 full moons. In addition to covering a broad area, it also covers a large span of time — more than 12 billion years.
Each tiny dot in the image at left is a galaxy simulated by the OpenUniverse campaign. The one-square-degree image offers a small window into the full simulation area, which is about 70 square degrees (equivalent to an area of sky covered by more than 300 full moons), while the inset at right is a close-up of an area 75 times smaller (1/600th the size of the full area). This simulation showcases the cosmos as NASA’s Nancy Grace Roman Space Telescope could see it. Roman will expand on the largest space-based galaxy survey like it – the Hubble Space Telescope’s COSMOS survey – which imaged two square degrees of sky over the course of 42 days. In only 250 days, Roman will view more than a thousand times more of the sky with the same resolution. The project’s immense space-time coverage shows scientists how the telescopes will help them explore some of the biggest cosmic mysteries. They will be able to study how dark energy (the mysterious force thought to be accelerating the universe’s expansion) and dark matter (invisible matter, seen only through its gravitational influence on regular matter) shape the cosmos and affect its fate. Scientists will get closer to understanding dark matter by studying its gravitational effects on visible matter. And by studying the simulation’s 100 million synthetic galaxies, they will see how galaxies and galaxy clusters evolved over eons.
Repeated mock observations of a particular slice of the universe enabled the team to stitch together movies that unveil exploding stars crackling across the synthetic cosmos like fireworks. These starbursts allow scientists to map the expansion of the simulated universe.
This simulation showcases the dynamic universe as NASA’s Nancy Grace Roman Space Telescope could see it over the course of its five-year primary mission. The video sparkles with synthetic supernovae from observations of the OpenUniverse simulated universe taken every five days (similar to the expected cadence of Roman’s High-Latitude Time-Domain Survey, which OpenUniverse simulates in its entirety). On top of the static sky of stars in the Milky Way and other galaxies, more than a million exploding stars flare into visibility and then slowly fade away. To highlight the dynamic physics happening and for visibility at this scale, the true brightness of each transient event has been magnified by a factor of 10,000 and no background light has been added to the simulated images. The video begins with Roman’s full field of view, which represents a single pointing of Roman’s camera, and then zooms into one square.NASA’s Goddard Space Flight Center and M. Troxel Scientists are now using OpenUniverse data as a testbed for creating an alert system to notify astronomers when Roman sees such phenomena. The system will flag these events and track the light they generate so astronomers can study them.
That’s critical because Roman will send back far too much data for scientists to comb through themselves. Teams are developing machine-learning algorithms to determine how best to filter through all the data to find and differentiate cosmic phenomena, like various types of exploding stars.
“Most of the difficulty is in figuring out whether what you saw was a special type of supernova that we can use to map how the universe is expanding, or something that is almost identical but useless for that goal,” said Alina Kiessling, a research scientist at NASA’s Jet Propulsion Laboratory (JPL) in Southern California and the principal investigator of OpenUniverse.
While Euclid is already actively scanning the cosmos, Rubin is set to begin operations late this year and Roman will launch by May 2027. Scientists can use the synthetic images to plan the upcoming telescopes’ observations and prepare to handle their data. This prep time is crucial because of the flood of data these telescopes will provide.
In terms of data volume, “Roman is going to blow away everything that’s been done from space in infrared and optical wavelengths before,” Troxel said. “For one of Roman’s surveys, it will take less than a year to do observations that would take the Hubble or James Webb space telescopes around a thousand years. The sheer number of objects Roman will sharply image will be transformative.”
This synthetic OpenUniverse animation shows the type of science that astronomers will be able to do with future Roman deep-field observations. The gravity of intervening galaxy clusters and dark matter can lens the light from farther objects, warping their appearance as shown in the animation. By studying the distorted light, astronomers can study elusive dark matter, which can only be measured indirectly through its gravitational effects on visible matter. As a bonus, this lensing also makes it easier to see the most distant galaxies whose light the dark matter magnifies. Caltech-IPAC/R. Hurt “We can expect an incredible array of exciting, potentially Nobel Prize-winning science to stem from Roman’s observations,” Kiessling said. “The mission will do things like unveil how the universe expanded over time, make 3D maps of galaxies and galaxy clusters, reveal new details about star formation and evolution — all things we simulated. So now we get to practice on the synthetic data so we can get right to the science when real observations begin.”
Astronomers will continue using the simulations after Roman launches for a cosmic game of spot the differences. Comparing real observations with synthetic ones will help scientists see how accurately their simulation predicts reality. Any discrepancies could hint at different physics at play in the universe than expected.
“If we see something that doesn’t quite agree with the standard model of cosmology, it will be extremely important to confirm that we’re really seeing new physics and not just misunderstanding something in the data,” said Katrin Heitmann, a cosmologist and deputy director of Argonne’s High Energy Physics division who managed the project’s supercomputer time. “Simulations are super useful for figuring that out.”
OpenUniverse, along with other simulation tools being developed by Roman’s Science Operations and Science Support centers, will prepare astronomers for the large datasets expected from Roman. The project brings together dozens of experts from NASA’s JPL, DOE’s Argonne, IPAC, and several U.S. universities to coordinate with the Roman Project Infrastructure Teams, SLAC, and the Rubin LSST DESC (Legacy Survey of Space and Time Dark Energy Science Collaboration). The Theta supercomputer was operated by the Argonne Leadership Computing Facility, a DOE Office of Science user facility.
The Nancy Grace Roman Space Telescope is managed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA’s Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science team comprising scientists from various research institutions. The primary industrial partners are BAE Systems, Inc in Boulder, Colorado; L3Harris Technologies in Rochester, New York; and Teledyne Scientific & Imaging in Thousand Oaks, California.

The crew of a Surjet private air service flight had an unusual encounter on December 23 while returning to Fort Lauderdale. Flight attendant Cassandra Martin, along with two pilots, was onboard the aircraft flying over the Bahamas when an unexpected event caught their attention.
“I suddenly heard air traffic control say, ‘We have a foreign object; can you please identify it?'” Martin recounted to NBC Miami.
Curious, she looked out the window. “I glanced to the left, and the pilot noticed three objects, though I only saw one. I quickly grabbed my phone, pressed it against the window, and tried to record a video of the object,” she explained.
Martin described the orb as white, later shifting to a faint green hue, almost as though surrounded by an electric field. The object followed their flight for about 45 minutes before disappearing.
What made the sighting extraordinary was the altitude. The jet was cruising at approximately 43,000 to 45,000 feet, yet the orb was far above the aircraft and still managed to track it for the extended duration.
The orb’s speed and maneuverability ruled out possibilities such as a balloon or a consumer drone. Unless the orb is of extraterrestrial origin, the orb might be a craft or drone equipped with highly advanced technology not yet publicly known, akin to recent reports of sophisticated drones spotted across the U.S.
This remarkable incident follows a December 16, 2024 sighting aboard United Airlines flight UA2359 from Chicago to Newark. During that flight, a passenger filmed several unidentified orbs at altitudes between 40,000 and 50,000 feet. Additionally, reports surfaced from at least four commercial airline pilots who witnessed mysterious, colorful, circular lights moving at extreme speeds over Oregon in the same month.
These repeated sightings raise questions: Are they advanced black projects hidden from public knowledge or evidence of something extraterrestrial? Regardless of their origin, the increasing reports of advanced drones and strange orbs suggest that something significant is occurring. View the full article

Newly Selected Citizen Science Proposals: A Peek at What’s Next
Last year, the NASA citizen science community saw a prize from the White House and two prizes from professional societies: one from the Division of Planetary Sciences and one from the American Astronomical Society. Our teams published two papers in the prestigious journal, Nature, one on a planetary crash and one about a distant world that seems to have auroras. 2024 was a year of 5000 comets, two solar eclipses and plenty of broken records.
But we’re not stopping to rest on our laurels. In 2024, NASA selected 25 new citizen science proposals for funding that will lead to new projects and new results to look forward to in 2025 and beyond. Here’s a roundup of those selections and the principal investigators (PIs) of each team—a sneak peek at what’s coming next in NASA citizen science! Note that these investigations are research grants–some of them will result in new opportunities for the public, others will use results from earlier citizen science projects or develop new tools.

On Jan. 9, 1990, space shuttle Columbia took off on its ninth flight, STS-32, from NASA’s Kennedy Space Center (KSC) in Florida. Its five-person crew of Commander Daniel Brandenstein, Pilot James Wetherbee, and Mission Specialists Bonnie Dunbar, Marsha Ivins, and David Low flew a then record-breaking 11-day mission to deploy the Syncom IV-F5 communications satellite for the U.S. Navy and retrieve the Long-Duration Exposure Facility (LDEF). Astronauts aboard a shuttle mission in 1984 deployed the LDEF and scientists eagerly awaited the return of their 57 experiments to study the effects of nearly six years exposure to the low Earth orbit environment. The crew also conducted several middeck experiments in biotechnology and materials processing and used an echocardiograph to study changes in their hearts.
The STS-32 crew of Mission Specialist Bonnie Dunbar, left, Commander Daniel Brandenstein, Pilot James Wetherbee, and Mission Specialists Marsha Ivins and David Low. The STS-32 crew patch. The Long Duration Exposure Facility during its deployment on the STS-41C mission in 1984. In November 1988, NASA announced Brandenstein, Wetherbee, Dunbar, Ivins, and Low as the STS-32 crew for the flight then planned for November 1989. Brandenstein, from the Class of 1978, had flown twice before, as pilot on STS-8 in August-September 1983 and commander of STS-51G in June 1985. Dunbar, selected in 1980, had flown once before on STS-61A in October-November 1985. For Wetherbee, Ivins, and Low, all selected in 1984, STS-32 marked their first spaceflight. During the second day of their planned 10-day mission, the astronauts would deploy the Syncom IV-F5, also known as Leasat-5, communications satellite for the U.S. Navy. The main focus of the flight involved the retrieval of LDEF, deployed by the STS-41C crew in April 1984. The original plan had LDEF, containing 57 science and technology experiments, retrieved by the STS-51D crew in February 1985. Delays in the shuttle program first pushed the retrieval to STS-61I in September 1986, and then the Challenger accident delayed it to STS-32. The facility ended up staying in orbit nearly six years instead of the originally intended 10 months. The crew rounded out the mission by conducting a series of middeck science and medical experiments.
Space shuttle Columbia rolls out to its launch pad on a foggy morning. NASA scientist John Charles, at rear, trains astronauts David Low, left, and Bonnie Dunbar, supine, in the operation of a cardiovascular experiment. The STS-32 crew exits crew quarters for the ride to Launch Pad 39A. Columbia returned to KSC on Aug. 21, 1989, following STS-28’s landing at Edwards Air Force Base (AFB) in California, and workers towed it to the Orbiter Processing Facility (OPF) the next day. They made 26 modifications to the orbiter, including the installation of the Remote Manipulator System (RMS), or robotic arm, and a fifth set of liquid hydrogen and liquid oxygen tanks to extend the vehicle’s duration in space. Rollover to the nearby Vehicle Assembly Building took place on Nov. 16, where Columbia joined its External Tank and twin Solid Rocket Boosters (SRB) on refurbished Mobile Launch Platform 3, last used in 1975. Rollout took place on Nov. 28 to Launch Pad 39A, newly refurbished since its previous launch in 1986.
On Dec. 1, engineers and the astronaut crew completed the Terminal Countdown Demonstration Test, a dress rehearsal for the planned Dec. 18 launch. Based on that date and the mission’s planned 10-day duration, the STS-32 crew would have spent Christmas in space, only the third American crew and the first space shuttle crew to do so. However, unfinished work on Pad 39A delayed the launch into January 1990. Trajectory specialists had estimated that due to orbital decay, LDEF would reenter the Earth’s atmosphere by March 1990, so a timely launch remained crucial for mission success. The countdown began on Jan. 4 for an expected Jan. 8 launch, with the crew arriving at KSC on Jan. 5.
Liftoff of space shuttle Columbia on STS-32. The deployment of the Syncom IV-F5 satellite. Syncom following deployment. Cloudy skies scrubbed the first launch attempt on Jan. 8. Liftoff took place the next day at 7:35 a.m. EST from Launch Pad 39A, with LDEF 1,500 miles ahead of Columbia. The powered ride to space took 8.5 minutes, placing Columbia into a 215-by-38-mile orbit. A burn of the two Orbiter Maneuvering System (OMS) engines 40 minutes later changed the orbit to the desired 222-by-180-mile altitude. The crew opened the shuttle’s payload bay doors and deployed its radiators. The major activities for the first day in space involved the checkout of the RMS and the first rendezvous maneuver in preparation for the LDEF grapple three days later. The astronauts also activated four of the middeck experiments. On the mission’s second day, Low deployed the 15,000-pound Syncom satellite, releasing it in a frisbee motion out of the payload bay. The satellite extended its antenna, stabilized itself, and 40 minutes after deployment, fired its engine for the first burn to send it to its geostationary orbit.
The Long Duration Exposure Facility (LDEF) during the rendezvous. STS-32 astronaut Bonnie Dunbar has grappled LDEF with the Remote Manipulator System. Dunbar lowers LDEF into the payload bay. Following the Syncom deploy, the crew turned its attention to the rendezvous with LDEF while also continuing the middeck experiments. On Flight Day 3, they completed three rendezvous burns as they steadily continued their approach to LDEF. Soon after awakening on Flight Day 4, the astronauts spotted LDEF appearing as a bright star. After the first of four rendezvous burns, Columbia’s radar locked onto the satellite. As they continued the approach, with three more burns carried out successfully, Dunbar activated the RMS in preparation for the upcoming grapple. Brandenstein took over manual control of Columbia for the final approach and parked the shuttle close enough to LDEF for Dunbar to reach out with the 50-foot arm and grapple the satellite. Brandenstein reported, “We have LDEF.”
For the next four hours, with Wetherbee flying the orbiter and Dunbar operating the arm, Ivins performed a comprehensive photo survey of LDEF, documenting the effects of nearly six years of space exposure on the various experiments. The survey completed, Dunbar slowly and carefully lowered LDEF into the payload bay, and five latches secured it in place for the ride back to Earth. With the two major goals of their mission completed, the astronauts settled down for the remainder of their 10-day mission conducting science experiments.
With astronaut David Low acting as an operator, astronaut Bonnie Dunbar serves as a subject for a cardiovascular experiment. Astronaut Marsha Ivins with several cameras testing the effects of spaceflight on different types of film. During the mission, the STS-32 crew conducted several middeck experiments. The Protein Crystal Growth experiment used vapor diffusion to grow 120 crystals of 24 different proteins, for study by scientists following their return to Earth. The Characterization of Neurospora Circadian Rhythm experiment studied whether spaceflight affected the daily cycles of pink bread mold. The Fluid Experiment Apparatus performed materials processing research in the microgravity environment. The astronauts used the American Flight Echocardiograph (AFE) to study changes in their hearts as a result of weightlessness. The crew used the large format IMAX camera to film scenes inside the cabin as well as through the windows, such as the capture of LDEF.
Astronaut Daniel Brandenstein holds an inflatable plastic cake given to him by his crew mates in honor of his birthday. The STS-32 crew poses in Columbia’s middeck. On Jan. 17, Brandenstein celebrated his 47th birthday, the fifth American astronaut to do so in space. His crew presented him with an inflatable plastic cake including candles while controllers in Mission Control passed on their birthday wishes as did his wife and teenage daughter. On the same day, NASA announced the selection of its 13th group of astronauts. Among them, engineer Ronald Sega, Dunbar’s husband, as well as the first female shuttle pilot, Eileen Collins, and the first Hispanic woman astronaut, Ellen Ochoa.
Columbia touches down at Edwards Air Force Base in California. At the welcome home ceremony at Ellington Field in Houston, director of NASA’s Johnson Space Center Aaron Cohen addresses the crowd as the STS-32 astronauts and their families listen. On Jan. 19, the astronauts awakened for their planned final day in space. However, due to fog at their landing site, Edwards AFB in California, Mission Control first informed them that they would have to spend an extra orbit in space, and finally decided to delay the landing by an entire day. With their experiments already packed, the crew spent a quiet day, looking at the Earth and using up what film still remained. As they slept that night, they passed the record for the longest space shuttle mission, set by STS-9 in 1983.
In preparation for reentry, the astronauts donned their orange spacesuits and closed the payload bay doors. A last-minute computer problem delayed reentry by one orbit, then Brandenstein and Wetherbee oriented Columbia into the deorbit attitude, with the OMS engines facing in the direction of travel. Over the Indian Ocean, they fired the two engines for 2 minutes 48 seconds to bring the spacecraft out of orbit. They reoriented the orbiter to fly with its heat shield exposed to the direction of flight as it encountered Earth’s atmosphere at 419,000 feet. The buildup of ionized gases caused by the heat of reentry prevented communications for about 15 minutes but provided the astronauts a great light show. After completing the Heading Alignment Circle turn, Brandenstein aligned Columbia with the runway, and Wetherbee lowered the landing gear. Columbia touched down and rolled to a stop, making the third night landing of the shuttle program and ending a 10-day 21-hour 1-minute flight, the longest shuttle flight up to that time, having completed 172 orbits of the Earth.
Other records set by the astronauts on this mission included Brandenstein as the new record holder for most time spent in space by a shuttle crew member – 24 days – and Dunbar accumulating the most time in space by a woman – 18 days – up to that time. Following eight hours of postflight medical testing, the astronauts boarded a jet bound for Houston’s Ellington Field, where they reunited with their families and took part in a welcome home ceremony led by Aaron Cohen, director of NASA’s Johnson Space Center.
Columbia returns to NASA’s Kennedy Space Center in Florida atop the Shuttle Carrier Aircraft. Workers lift the Long Duration Exposure Facility from Columbia’s payload bay. Following postlanding inspections, workers placed Columbia, with LDEF still cradled in its payload bay, atop a Shuttle Carrier Aircraft, a modified Boeing-747, and the combination left Edwards on Jan. 25. Following a refueling stop at Monthan Davis AFB in Tucson, an overnight stay at Kelly AFB in San Antonio, and another refueling stop at Eglin AFB in Fort Walton Beach, Florida, Columbia and LDEF arrived back at KSC on Jan. 26. The next day, workers towed Columbia to the OPF and on Jan. 30 lifted LDEF out of its payload bay, in preparation for the detailed study of the effects of nearly six years in space on the 57 experiments it carried. Meanwhile, workers began to prepare Columbia for its next flight, STS-35 in December 1990.
