Expedition 74 focused on installing CubeSats and observing Earth aboard the International Space Station on Thursday. The trio from NASA and Roscosmos kept up ongoing research operations along with standard orbital lab maintenance throughout the day.
Scouring archived observations from NASA missions, scientists may have solved a mystery about what powers a type of aurora called auroral arcs. The answer, they say, is space waves. From the ground, auroral arcs look like green, glowing curtains of light sweeping across…
New analysis of decades-old data has turned up a significant result: the first discovery of ammonia-bearing compounds on the surface of Jupiter’s moon Europa. Ammonia is a nitrogen-bearing molecule, and nitrogen — like carbon, hydrogen, and oxygen — is key…
A total lunar eclipse will redden the Moon on March 3, 2026. Here’s what you need to know.
A mild La Niña caused greater rainfall over the Amazon basin, which offset rising sea levels due to record warming of Earth’s oceans. The rise in the global mean sea level slowed in 2025 relative to the year before, an…
New simulations performed on a NASA supercomputer are providing scientists with the most comprehensive look yet into the maelstrom of interacting magnetic structures around city-sized neutron stars in the moments before they crash. The team identified potential signals emitted during…
Technicians have completed the construction of NASA’s Nancy Grace Roman Space Telescope. The Roman observatory is slated to launch no later than May 2027, with the team aiming for as early as fall 2026. The mission will revolutionize our understanding…
Very wet—but very warm—weather in the western U.S. has left many mountainous regions looking at substantial snowpack deficits.
The four crew members of NASA’s SpaceX Crew-12 mission began their routine two-week quarantine on Wednesday at NASA’s Johnson Space Center in Houston ahead of their upcoming launch to the International Space Station. The earliest opportunity for Crew-12 to launch to the…
Robotics and artificial intelligence were back on the research schedule Wednesday for the Expedition 74 crew to inspire college students and explore boosting crew efficiency. Earth observations and life support maintenance also rounded out the day for the orbital residents…
