New computer simulations suggest the first magnetic fields that emerged after the Big Bang were much weaker than expected — containing the equivalent magnetic energy of a human brain.

Four research volunteers will soon participate in NASA’s year-long simulation of a Mars mission inside a habitat at the agency’s Johnson Space Center in Houston. This mission will provide NASA with foundational data to inform human exploration of the Moon, Mars, and beyond. Ross Elder, Ellen Ellis, Matthew Montgomery, and James Spicer enter into the […]

NASA is requesting feedback from American companies on the next phase of its commercial space stations strategy to ensure a seamless transition of activities in low Earth orbit from the International Space Station. The agency released a draft Phase 2 Announcement for Partnership Proposals (AFPP) Friday, asking for feedback from industry partners by 1 p.m. […]

This long-exposure photograph, taken over 31 minutes from a window inside the International Space Station’s Kibo laboratory module, captures the graceful arcs of star trails.

Sea ice is frozen seawater that floats in the ocean. This photo, taken from NASA’s Gulfstream V Research Aircraft on July 21, 2022, shows Arctic sea ice in the Lincoln Sea north of Greenland.

NASA astronauts Jonny Kim and Zena Cardman, both Expedition 73 Flight Engineers, pose for a portrait inside the International Space Station's Unity module during a break in weekend housecleaning and maintenance activities. Kim and Cardman are both part of NASA Astronaut Group 22 selected in June 2017 with 12 other astronauts, including two Canadian Space Agency astronauts, and affectionately nicknamed «The Turtles.»

Orion Mission Evaluation Room (MER) team member works during an Artemis II mission simulation on Aug. 19, 2025, from the new Orion MER inside the Mission Control Center at NASA’s Johnson Space Center in Houston.

Scientists have studied female monkey embryos to map how, when and where the egg supply develops. This can now be used to build realistic models of ovaries in the lab to search for the causes of reproductive health issues that lead to infertility.

A 100-year-old theory explaining how Asia can carry the huge weight of the Himalayas and Tibetan Plateau needs to be rewritten, a new study suggests.

Ranking who has the best ears in the animal kingdom is a tough task, but some animals push the limits of hearing far beyond what humans can imagine.

On Aug. 23, 1966, NASA's Lunar Orbiter 1 sent back the first photo of Earth from the moon. It showed a grainy crescent Earth that predated Apollo 8's famous color «Earthrise» by over two years.

NASA will hold a media teleconference at 12 p.m. EDT on Thursday, Sept. 4, to discuss the agency’s upcoming Sun and space weather missions, IMAP (Interstellar Mapping and Acceleration Probe) and Carruthers Geocorona Observatory. The two missions are targeting launch on the same rocket no earlier than Tuesday, Sept. 23. The IMAP mission will map […]

NASA has awarded ASCEND Aerospace & Technology of Cape Canaveral, Florida, the Contract for Organizing Spaceflight Mission Operations and Systems (COSMOS), to provide services at the agency’s Johnson Space Center in Houston. The COSMOS is a single award, indefinite-delivery/indefinite-quantity contract valued at $1.8 billion that begins its five-year base period no earlier than Dec. 1, […]

This NASA/ESA Hubble Space Telescope image features a galaxy whose asymmetric appearance may be the result of a galactic tug of war. Located 35 million light-years away in the constellation Leo, the spiral galaxy Messier 96 is the brightest of the galaxies in its group. The gravitational pull of its galactic neighbors may be responsible […]

The Operational Land Imager on Landsat 9 captured this image of Buccaneer Archipelago on June 11, 2025. The scene encapsulates the striking interactions between land and water in the area where King Sound opens to the Indian Ocean. The powerful tidal currents stir up sediment in shallow areas, producing the beautiful turquoise swirls visible in this image. This […]

NASA astronaut Megan McArthur has retired, concluding a career spanning more than two decades. A veteran of two spaceflights, McArthur logged 213 days in space, including being the first woman to pilot a SpaceX Dragon spacecraft and the last person to “touch” the Hubble Space Telescope with the space shuttle’s robotic arm. McArthur launched as […]

Early Earth may not have had the right ingredients for life — until a nearby Mars-size planet crashed into it, two new studies hint.
