An artist’s concept of a supermassive black hole, a surrounding disk of material falling towards the black hole and a jet containing particles moving away at close to the speed of light. This black hole represents a recently-discovered quasar powered by a black hole. New Chandra observations indicate that the black hole is growing at [...]

5 min read New NASA Mission to Reveal Earth’s Invisible ‘Halo’ A new NASA mission will capture images of Earth’s invisible “halo,” the faint light given off by our planet’s outermost atmospheric layer, the exosphere, as it morphs and changes in response to the Sun. Understanding the physics of the exosphere is a key [...]

NASA; JAXA The Milky Way appears above Earth’s bright atmospheric glow in this Aug. 23, 2025, photograph from the International Space Station as it soared 261 miles above southern Iran at approximately 12:54 a.m. local time. The camera was configured for low light and long duration settings. Our home galaxy has hundreds of billions of [...]

NASA’s Artemis II SLS (Space Launch System) rocket poised to send four astronauts from Earth on a journey around the Moon next year may appear identical to the Artemis I SLS rocket. On closer inspection, though, engineers have upgraded the agency’s Moon rocket inside and out to improve performance, reliability, and safety. SLS flew a [...]

With every new discovery, scientists move closer to answering whether there are other planets like Earth that could host life as we know it. NASA/JPL-Caltech The milestone [...]

Technicians completed integrating NASA’s Carruthers Geocorona Observatory and the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Follow-On Lagrange 1 (SWFO-L1) satellite to an Evolved Expendable Launch Vehicle Secondary Payload Adapter ring at the Astrotech Space Operations Facility near NASA’s Kennedy Space Center in Florida on Sept. 4. Integrating the rideshares to the ring [...]

NASA/Jonny Kim NASA astronaut Zena Cardman processes bone cell samples inside the Kibo laboratory module’s Life Science Glovebox on Aug. 28, 2025, as part of an experiment that tests how microgravity affects bone-forming and bone-degrading cells and explore potential ways to prevent bone loss. This research could help protect astronauts on future long-duration missions to [...]
