NASA’s CloudSat Ends Mission Peering Into the Heart of Clouds
2024.04.23
CloudSat, a NASA mission that peered into hurricanes, tallied global snowfall rates, and achieved other weather and climate firsts, has ended its operations. Originally proposed as a 22-month mission, the spacecraft was recently decommissioned after almost 18 years observing the vertical structure and ice/water content of clouds.

Hubble Celebrates 34th Anniversary with a Look at the Little Dumbbell Nebula
2024.04.23
In celebration of the 34th anniversary of the launch of NASA’s legendary Hubble Space Telescope on April 24, astronomers took a snapshot of the Little Dumbbell Nebula (also known as Messier 76, M76, or NGC 650/651) located 3,400 light-years away in the northern circumpolar constellation Perseus. The photogenic nebula is a favorite target of amateur astronomers. M76 […]

Join NASA in Celebrating Earth Day 2024 by Sharing a #GlobalSelfie
2024.04.19
NASA invites you — and everyone else on the planet — to take part in a worldwide celebration of Earth Day with the agency’s #GlobalSelfie event. While NASA satellites constantly look at Earth from space, on Earth Day we’re asking you to step outside and take a picture of yourself in your corner of the world.
NASA Data Helps Beavers Build Back Streams
2024.04.19
Humans aren’t the only mammals working to mitigate the effects of climate change in the Western United States. People there are also enlisting the aid of nature’s most prolific engineers – beavers. Using NASA-provided grants, two open-source programs from Boise State University in Idaho and Utah State University in Logan are making it possible for […]
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 […]
AI for Earth: How NASA’s Artificial Intelligence and Open Science Efforts Combat Climate Change
2024.04.18
As extreme weather events increase around the world due to climate change, the need for further research into our warming planet has increased as well. For NASA, climate research involves not only conducting studies of these events, but also empowering outside researchers to do the same. The artificial intelligence (AI) efforts spearheaded by the..
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. […]
Spring Floods Sweep Across Central Asia
2024.04.17
Rivers overtopped their banks and submerged thousands of homes in Russia and Kazakhstan.
NASA’s TESS Returns to Science Operations
2024.04.17
NASA’s TESS (Transiting Exoplanet Survey Satellite) has returned to work after science observations were suspended on April 8, when the spacecraft entered into safe mode. All instruments are powered on and, following the successful download of previously collected science data stored in the mission’s recorder, are now making new science observation
NASA Invites Media for Climate Update, New Earth Missions
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

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 […]
