Phil Kaaret (ST12) is lead author on the paper which describes Chandra X-ray Observatory observations of the galaxy NGC 2366. Escape of Lyman continuum (LyC) emission from galaxies found in the early universe was essential for the reionization of the universe when the intergalactic medium (IGM) changed from being neutral gas to the ionized IGM that we observe today. Compact emission-line galaxies (LCGs) are the most abundant class of confirmed Lyman continuum (LyC) emitters and provide (relatively) nearby analogs of the galaxies found in the early universe. An optical integral field study of NGC 2366 revealed an outflow originating at a star cluster known as “knot B” that is thought to clear a channel via mechanical feedback that enables LyC escape. We observed NGC 2366 with the Chandra and detected X-ray emission from a point source coincident with the apex of the outflow at knot B. The pointlike nature and variability of the X-ray emission suggests accretion onto a compact object in an X-ray binary. The accretion could produce sufficient kinetic energy to power the outflow. Thus, outflows from X-ray binaries may be important in enabling LyC emission from galaxies. Read more at: https://arxiv.org/abs/2405.13192. Illustration of ChandraView the full article

This work will enable a more process-oriented look at how convectively driven cold pools interact with convection and the local environment. Data from NASA precipitation sensors and NOAA geostationary observations will be included in the analysis as well. The project will last for three years, and it includes University of Alabama in Huntsville (Co-I George Priftis) as a local partner. View the full article

Timothy Lang (ST11) is a co-author on an article titled “Effective Visualization of Radar Data for Users Impacted by Color Vision Deficiency”, which was recently accepted for publication in Bulletin of the American Meteorological Society. The article is led by Zachary Sherman of Argonne National Laboratory (ANL), and it is an outgrowth of a long-standing collaboration on open science between ANL, MSFC, and other institutions that predates NASA Science Policy Directive (SPD) 41a and the Transform to Open Science (TOPS) campaign. Color Vision Deficiency (CVD) affects up to 8% of genetic males and 0.5% of genetic females, and traditional color maps used in radar meteorology and other Earth sciences often lack perceptual accuracy and clarity when viewed by those affected by CVD. The article reviews new color maps that convey useful and clear scientific information whether viewed by those with normal color perception or those with CVD. These color maps are available in open-source repositories like cmweather (https://github.com/openradar/cmweather) and pyart (http://arm-doe.github.io/pyart/). The article and the open-source CVD-friendly color maps are excellent examples of the greater inclusivity fostered when open science is practiced.

Linda Krause and Heidi Haviland (ST13) along with Jeff Apple, Miguel Rodriguez-Otero (ES11), Kurt Dietz (ES52), and Gary Thornton (ES21) contributed to the Planetary Instrument Concepts for the Advancement of Solar System Observations (PICASSO) proposal LVACCS that was selected for funding. Omar Leon (University of Michigan) is the instrument suite PI. Electric charge accumulates on the lunar rovers and landers from ambient plasma, ionizing radiation, suprathermal charged particles, dust, and surface regolith. LVACCS will measure both the positive and negative charge, acts to discharge negative charge buildup, and actively charges the vehicle to a known positive potential. This increases the accuracy and precision of related instruments including dust, plasma, and electric fields. LVACCS builds from heritage systems in geosynchronous orbit but with a much smaller size, weight, and power. LVACCS has two main components: a collimated photoelectron gun (CPEG, led by MSFC), and a spacecraft charge detector (led by the University of Michigan). Within the two years of the award, the instrument will mature from TRL 2 to 5. LVACCS solves the important and timely problem of charge build up at the lunar surface for future lander and rover missions. View the full article

NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado (CU) Boulder enacted a collaborative Space Act Agreement Monday, Aug. 5, 2024, to advance research and modeling in the critical field of space weather. NASA and LASP are longtime space science and exploration partners, and this formal agreement expands the depth and breadth of space weather activities for everyone’s benefit. Space weather refers to conditions in space — typically driven by the Sun’s activity — that can affect humans and technology. Space weather is responsible for the aurora, and intense events can harm spacecraft, astronauts, or even technology on Earth. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado (CU) Boulder enacted a collaborative Space Act Agreement to advance research and modeling in the critical field of space weather. Goddard Center Director Dr. Makenzie Lystrup (left) and LASP Director Dr. Daniel Baker signed the agreement Monday, Aug. 5, 2024.NASA/Bri Horton “Space weather touches all aspects of life, from our power grid to space-based assets that are susceptible to space weather events,” said Dr. Makenzie Lystrup, NASA Goddard director. “This agreement today formalizes a long-standing collaboration with LASP essential to expanding space weather applications that protect ground- and space-based assets, not to mention our astronauts preparing to explore deeper into space to the Moon and beyond.” LASP is at the forefront of solar, planetary, and space physics research, climate and space-weather monitoring, and the search for evidence of habitable worlds, all of which match perfectly with Goddard’s mission portfolio and leadership in heliophysics research. “We have had a long and highly productive partnership with NASA’s Goddard Space Flight Center in all areas of space exploration,” said LASP Director Dr. Daniel Baker. “It is now an honor for LASP to collaborate with the world’s largest Earth and space science research organization to advance our nation’s space weather and heliophysics capabilities. This agreement offers new opportunities to learn from our overlapping space weather expertise and to leverage scientific research using small satellites.” The agreement calls for a more formal and robust framework to expand space weather work in several key areas, to include: Maturation and miniaturization of instruments for space weather research Incorporating space weather instrumentation and packages as hosted payloads on satellites Exploring joint work in “Space Weather Research to Operations” activities Addressing important aspects of space weather policy And, defining best practices for mission proposal development Goddard is NASA’s premiere spaceflight complex and home to the nation’s largest organization of scientists, engineers, and technologists who build spacecraft, instruments, and new technology to study Earth, the Sun, our solar system, and the universe.

Analyses suggest that microgravity does not significantly alter fundamental biochemical pathways in kidney cells, including metabolism of vitamin D. This finding could help researchers develop strategies to protect crew health on future missions and improve treatment of kidney-related diseases on Earth. Kidney Cell examined the effects of microgravity and other factors of space travel on kidney health. Previous reports suggested that changes in kidney cell metabolism of vitamin D plays a role in bone loss in microgravity, and this paper recommends additional study to determine if this most recent finding is consistent with extended (>6 months) exposure to microgravity. NASA astronaut Christina Koch works inside the Life Sciences Glovebox on the International Space Station with the Kidney Cells experiment to examine how kidney health is affected by microgravity and other factors of space travel, including increased chemical exposure, water conservation, recycling, and altered dietary intake. NASA/Nick Hague From cosmic rays collected by AMS-02 (Alpha Magnetic Spectrometer) between May 2011 and April 2021, researchers report precise measurements of the behavior of cosmic deuterons. These data provide important clues in the search for dark matter and understanding of the overall nature of the universe. AMS-02 is an alpha-magnetic spectrometer that looks for evidence of dark matter. To date, AMS-02 has collected more than 180 billion events of galactic cosmic rays. Hydrogen nuclei, the most abundant type of cosmic rays, consist of two stable isotopes, protons and deuterons, believed to have been generated by the Big Bang. Exterior view of the International Space Station during an extravehicular activity with a fisheye camera. Researchers identified multiple proteins in rodents that are associated with bone and muscle loss in microgravity. This finding helps researchers understand physiological adaptation to spaceflight. JAXA’s (Japan Aerospace Exploration Agency) Medical Proteomics analyzed changes in protein expression in the blood, bone, and muscles of mice after spaceflight to identify specific proteins related to bone loss. Combined data from the space-flown mice, astronauts, and patients on Earth helps clarify the relationship between bone loss in microgravity and on the ground. View the full article

Learn Home AstroViz: Iconic Pillars of… For Educators Overview Learning Resources Science Activation Teams SME Map Opportunities More Science Stories Science Activation Highlights Citizen Science 4 min read AstroViz: Iconic Pillars of Creation Star in NASA’s New 3D Visualization NASA’s Universe of Learning – a partnership among the Space Telescope Science Institute (STScI), Caltech/IPAC, the Center for Astrophysics | Harvard & Smithsonian, and the Jet Propulsion Laboratory and part of the NASA Science Activation program portfolio – recently released a new 3D visualization of the towering clouds of cosmic dust and gas at the center of the star-forming region known as M16, or the Eagle Nebula. This video, which uses data from NASA’s Hubble, James Webb, and Spitzer space telescopes, as well as the Chandra X-ray Observatory, is the most comprehensive and detailed multiwavelength movie yet of these star-birthing “Pillars of Creation.” “By flying past and amongst the pillars, viewers experience their three-dimensional structure and see how they look different in the Hubble visible light view versus the Webb infrared light view,” explained principal visualization scientist Frank Summers of STScI in Baltimore. “The contrast helps them understand why we have more than one space telescope to observe different aspects of the same object.” Summers led the video development team. The Pillars of Creation, made primarily of cool molecular hydrogen and dust, are being eroded by the fierce winds and punishing ultraviolet light of nearby hot, young stars. Finger-like structures larger than the solar system protrude from the tops of the pillars. Within these fingers can be embedded embryonic stars. The tallest pillar stretches across three light-years, three-quarters of the distance between our Sun and the next nearest star. The movie takes visitors into the three-dimensional structures of the pillars. Rather than an artistic interpretation, the video is based on observational data from a science paper led by Anna McLeod, an associate professor at the University of Durham in the United Kingdom. McLeod also served as a scientific advisor on the movie project. The 3D structures are approximations for how the pillars are lined up in space like a row of trees, based on observational data. The goal is to give viewers an experiential view, so that they can better interpret the otherwise flat, two-dimensional images from telescopes. This 3D understanding allowed the team to create 3D printable files of the Pillars using the newest data. On the same day or the visualization release, Dr. Frank Summers led a live-streamed panel discussion with attendees covering “A Deep Dive into the Creation of the Pillars of Creation” at the AstroViz Community Practice meetup. The panelists and attendees engaged in a deep dive into the transformation of 2D views of the Pillars of Creation into a scientifically-vetted 3D visualization. The new visualization helps viewers experience how of the world’s most powerful space telescopes work together to provide a more complex portrait of the pillars. Hubble sees objects that glow in visible light at thousands of degrees. Webb’s infrared vision, which is sensitive to cooler objects with temperatures of just hundreds of degrees, pierces through obscuring dust to see stars embedded in the pillars.

4 Min Read NASA, EPA Tackle NO2 Air Pollution in Overburdened Communities This map shows average concentrations of nitrogen dioxide for 2022 over the U.S., as detected by the Ozone Monitoring Instrument on NASA’s Aura satellite. Higher concentrations are in red and purple. Lower concentrations are in blue. Credits: NASA’s Scientific Visualization Studio Earth (ESD) Earth Home Explore Climate Change Science in Action Multimedia Data For Researchers For the first time, NASA data about nitrogen dioxide (NO2), a harmful air pollutant, is available in the Environmental Protection Agency’s (EPA) widely used Environmental Justice Screening and Mapping Tool (EJScreen). This update marks a crucial step in addressing air quality disparities in overburdened communities across the United States. “Having access to this accurate and localized NO2 data allows organizations like ours to understand the air quality challenges we encounter, and to advocate more effectively for the health and well-being of community residents,” said Samuel Jordan, president of the Baltimore Transit Equity Coalition. Previously, EJScreen included data on ozone, fine particulate matter, and various other environmental hazards. But it lacked information on NO2, which has been linked to respiratory issues such as asthma, especially in children. “Incorporating NO2 data into EJScreen is a testament to how NASA’s Earth science capabilities can be applied to address crucial societal challenges,” said John Haynes, NASA’s program manager for Health and Air Quality. “This collaboration with the EPA underscores our commitment to using space-based observations to benefit public health and environmental justice.” NO2 is emitted by burning fossil fuels and contributes to the formation of surface ozone. Communities of color and lower-income populations often live closer to highways, factories, transportation hubs, and other NO2 sources than their wealthier counterparts. As a result, residents are exposed to higher levels of this air pollutant and others, exacerbating health inequalities. For example, a new NASA-funded study used satellite data and other information to show that nearly 150,000 warehouses in the U.S. increase local NO2 levels and are predominantly located in marginalized communities. The findings reveal a 20% increase, on average, in near-warehouse NO2, linked to truck traffic and warehouse density. “NO2 is very short-lived in the air, and so its levels are high in the area where it is emitted,” said Gaige Kerr, study coauthor and an air pollution researcher at George Washington University in Washington, who was involved in incorporating NASA’s NO2 data into EJScreen. “This tool democratizes access to high-quality NO2 data, allowing individuals without a background in data analysis or data visualization to access and understand the information easily.” EJScreen uses data from the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite and computer models to provide average annual NO2estimates at the census block level, revealing the amount of chronic surface-level NO2 that people may be exposed to in their neighborhoods. “Satellite data has the potential to transform the measurement of certain environmental and climate factors,” said Tai Lung, an environmental protection specialist with EPA and EJScreen lead. “The consistency of NASA’s NO2 data for every corner of the U.S. makes it tremendously valuable for screening and mapping of disproportionate impacts in communities.” The dataset was developed with contributions from George Washington University, the University of Washington School of Medicine in Seattle, and Oregon State University in Corvallis. The data integration was made possible through a NASA grant to the Satellite Data for Environmental Justice Tiger Team (part of NASA’s Health and Air Quality Applied Sciences Team), which worked closely with the EPA to ensure the data’s accuracy and relevance. NASA uses a variety of instruments on satellites, aircraft, and ground stations to continually gather data on key air pollutants. Scientists supported by NASA and other researchers monitor the origins, levels, and atmospheric movement of these pollutants. Their research offers crucial Earth-observation data that can guide air quality standards, shape public policies, and inform government regulations, ultimately aiming to enhance economic and human welfare. The Aura satellite recently celebrated its 20-year anniversary. In the future, Kerr said, the team could explore using NO2 data from NASA’s new TEMPO (Tropospheric Emissions: Monitoring of Pollution) instrument on the Intelsat commercial satellite. TEMPO launched in 2023 and offers hourly daytime measurements, rather than OMI’s once-daily measurements. This capability could further enhance the EPA tool, providing insight on pollution levels throughout the day and supporting proactive air pollution management.
