NASA is probing a sudden loss of contact with its MAVEN Mars orbiter after rare 3I/ATLAS data, raising questions about timing and the mission's future.

The X‑arithmetic technique offers a powerful new way to map the physics of other galactic structures across the universe and track how black holes shape their environments over millions of years. The findings were published Aug. 12 in the Astrophysical Journal.

Data from the James Webb Space Telescope suggests that exoplanet TOI-561 b is surrounded by a thick atmosphere above a global magma ocean.

NASA’s Chandra telescope uses a new X-arithmetic method to compare X-ray energies and show how supermassive black holes shape galaxy clusters and galaxy groups, revealing differences in gas movement a

The 84-foot-diameter space rock—dubbed "2025 XM"—is hurtling through the solar system at a zippy 9,753 miles per hour.

Cradled in the nose of a high-altitude research airplane, a new NASA sensor has taken to the skies to help geoscientists map rocks hosting lithium and other critical minerals on Earth's surface some 60,

Kim officially became an astronaut in 2017. Expedition 72 and Expedition 73 marked Kim’s first visit to the ISS, where he served as a flight engineer and flight surgeon for eight months while helping to conduct a number of scientific and technological research projects.

NASA astronaut Jonny Kim flew home with two Roscosmos cosmonauts from the International Space Station packed tight in their Soyuz spacecraft landing in the frozen steppes of Kazakhstan on Dec. 9 to complete an eight-month stay in space.

CINEMA, a mission to improve understanding of the growing impacts of space weather, has been competitively selected by NASA for development.
