The best known use of GPS satellites is to help people know their location whether driving a car, navigating a ship or plane, or trekking across remote territory. Another important, but lesser-known, use is to distribute information to other Earth-viewing satellites to help them pinpoint measurements of our planet.
Engineers are executing a comprehensive performance test to ensure the PACE spacecraft is ready for launch.
Kirk Knobelspiesse is an atmospheric scientist and the project science team polarimeter lead for PACE at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. He is also the polarimeter instrument scientist for the Atmosphere Observing System (AOS) constellation.
In 2023, The NASA Center for Climate Simulation (NCCS) and the NASA Science Managed Cloud Environment (SMCE) provided mission-critical, tailored computing resources to enable research and accelerate scientific discoveries that deepen our understanding of Earth and better prepare for its changing climates.
In the pre-dawn hours on Dec. 2, 1993, the space shuttle Endeavour launched from Kennedy Space Center in Florida on a critical mission to repair NASA’s Hubble Space Telescope.
This Hubble image features a massive cluster of brightly glowing galaxies, first identified as Abell 3192. Like all galaxy clusters, this one is suffused with hot gas that emits powerful X-rays, and it is enveloped in a halo of invisible dark matter.
Stuck on the seafloor for decades, Iceberg A-23A now freely drifts northward toward warmer, iceberg-destroying waters.
Six planets orbit their central star in a rhythmic beat, a rare case of an “in sync” gravitational lockstep that could offer deep insight into planet formation and evolution.
As part of the long-standing partnership between NASA and Google, NASA worked with Google Arts & Culture and artist Yiyun Kang to create an interactive digital experience around global freshwater resources titled “A Passage of Water.”
Many cities have shortages of air quality monitors. NASA scientists have developed a tool called GEOS-CF that can help.
An international team of astronomers has used NASA’s James Webb Space Telescope to provide the first observation of water and other molecules in the highly irradiated inner, rocky-planet-forming regions of a disk in one of the most extreme environments in our galaxy.
At SC23: The International Conference for High Performance Computing, Networking, Storage, and Analysis in Denver, Colorado, NASA Goddard scientists and technologists presented 12 research projects in NASA’s popular research exhibit.
The fiery and icy upper reaches of the Antarctic volcano pierced through a canopy of clouds.
Retired NASA astronaut Mary Cleave, a veteran of two NASA spaceflights, died Nov. 27. She was 76. A scientist with training in civil and environmental engineering, as well as biological sciences and microbial ecology, Cleave was the first woman to serve as an associate administrator for NASA’s Science Mission Directorate.
This new Picture of the Month from the NASA/ESA/CSA James Webb Space Telescope reveals intricate details of the Herbig Haro object 797 (HH 797). Herbig-Haro objects are luminous regions surrounding newborn stars (known as protostars), and are formed when stellar winds or jets of gas spewing from these newborn stars form shockwaves colliding with nearby gas and […]
Corrine Rojas is a scientific programmer in the ocean ecology lab at NASA’s Goddard Spaceflight Center.
A new catalog produced by a French-led international team of astronomers shows that NASA’s Fermi Gamma-ray Space Telescope has discovered 294 gamma-ray-emitting pulsars, while another 34 suspects await confirmation. This is 27 times the number known before the mission launched in 2008. “Pulsars touch on a wide range of astrophysics research, from cosmic rays and […]
A winter storm plowed across several U.S. states after Thanksgiving.
NASA Administrator Bill Nelson and other agency leaders will participate in the 28th United Nations Climate Change Conference of the Parties (COP28) beginning Thursday, Nov. 30, through Tuesday, Dec. 12, in Dubai, United Arab Emirates.
Ice cores and satellite images are helping preserve the history of a disappearing ice cap in the Peruvian Andes.
With 26 Earth-observing satellite missions, as well as instruments flying on planes and the space station, NASA has a global vantage point for studying our planet’s oceans, land, ice, and atmosphere and deciphering how changes in one drive change in others.
Fluid dynamics put on a spectacular show around Norway’s remote Bear Island.
Bethany Theiling is a planetary research scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
The latest image from NASA’s James Webb Space Telescope shows a portion of the dense center of our galaxy in unprecedented detail, including never-before-seen features astronomers have yet to explain. The star-forming region, named Sagittarius C (Sgr C), is about 300 light-years from the Milky Way’s central supermassive black hole, Sagittarius A*. Image: Sagittarius C […]
