Hubble Captures a Bright Galactic and Stellar Duo
2024.04.19
This image from the NASA/ESA Hubble Space Telescope features NGC 3783, a bright barred spiral galaxy about 130 million light-years from Earth that also lends its name to the eponymous NGC 3783 galaxy group. Like galaxy clusters, galaxy groups are aggregates of gravitationally bound galaxies. Galaxy groups, however, are less massive and contain fewer members than galaxy clusters […]
Hubble Goes Hunting for Small Main Belt Asteroids
2024.04.18
Like boulders, rocks, and pebbles scattered across a landscape, asteroids come in a wide range of sizes. Cataloging asteroids in space is tricky because they are faint and they don’t stop to be photographed as they zip along their orbits around the Sun. Astronomers recently used a trove of archived images taken by NASA’s Hubble […]
NASA’s Near Space Network Enables PACE Climate Mission to ‘Phone Home’
2024.04.17
The PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission has delivered its first operational data back to researchers, a feat made possible in part by innovative, data-storing technology from NASA’s Near Space Network, which introduced two key enhancements for PACE and other upcoming science missions. As a satellite orbits in space, its systems generate critical data […]
Tech Today: Taking Earth’s Pulse with NASA Satellites
2024.04.17
Natural disasters like volcanic eruptions, floods, and tornados can dramatically change the surface of Earth to the point where alterations are visible in space. Changes driven by human actions and interventions, such as mining and deforestation, are also visible in satellite imagery. For over 50 years, NASA’s Landsat satellites have recorded our planet’s changing surface. […]

2024.04.17
n anticipation of Earth Day, NASA invites media to a briefing at the agency’s headquarters on Friday, April 19, at 11 a.m. EDT. The event will share updates on NASA’s climate science and early data from the agency’s ocean-watching PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission, as well as reveal upcoming Earth airborne missions.
Astronauts To Patch Up NASA’s NICER Telescope
2024.04.17
NASA is planning to repair NICER (Neutron star Interior Composition Explorer), an X-ray telescope on the International Space Station, during a spacewalk later this year. It will be the fourth science observatory in orbit serviced by astronauts.
NASA’s Roman Space Telescope’s ‘Eyes’ Pass First Vision Test
2024.04.17
Engineers at L3Harris Technologies in Rochester, New York, have combined all 10 mirrors for NASA’s Nancy Grace Roman Space Telescope. Preliminary tests show the newly aligned optics, collectively called the IOA (Imaging Optics Assembly), will direct light into Roman’s science instruments extremely precisely. This will yield crisp images of space once the observatory launches. “This […]
NASA’s Fermi Mission Sees No Gamma Rays from Nearby Supernova
2024.04.16
A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA’s Fermi Gamma-ray Space Telescope detected none of the high-energy gamma-ray light those particles should produce. On May 18, 2023, a supernova erupted in the nearby […]
NASA’s Dragonfly Rotorcraft Mission to Saturn’s Moon Titan Confirmed
2024.04.16
NASA has confirmed its Dragonfly rotorcraft mission to Saturn’s organic-rich moon Titan. The decision allows the mission to progress to completion of final design, followed by the construction and testing of the entire spacecraft and science instruments. “Dragonfly is a spectacular science mission with broad community interest, and we are excited to take the next […]
Kate A. McGinnis: Ready to “Go” with PACE Testing
2024.04.16
PACE Systems Engineer Kate A. McGinnis spent years planning the vibration, acoustic, and shock tests for the PACE spacecraft before saying “Systems is ‘go’” to start each test.
The April 8 Total Solar Eclipse: Through the Eyes of NASA
2024.04.12
On April 8, 2024, the Moon’s shadow swept across North America, treating millions to a breathtaking view of a total solar eclipse. As the Moon passed in front of the Sun, it revealed the Sun’s wispy white outer atmosphere — the corona. Pictures of total solar eclipses are beautiful — they capture a moment happening […]
Hubble Spots a Galaxy Hidden in a Dark Cloud
2024.04.12
The subject of this image taken with the NASA/ESA Hubble Space Telescope is the spiral galaxy IC 4633, located 100 million light-years away from us in the constellation Apus. IC 4633 is a galaxy rich in star-forming activity and also hosts an active galactic nucleus at its core. From our point of view, the galaxy […]
A “Surprisingly Average” Year for Sierra Snowpack
