A new European Southern Observatory (ESO) study has found that current proposals to launch more than 1.7 million satellites into orbit, including extremely bright ones, would have "devastating consequences for astronomy.

If the number of satellites in Earth's orbit exceeds 100,000, humanity may lose its ability to study the universe from the planet's surface.

Shenlong launched in February for its fourth mission, although there's still little information on the experimental vehicle.

At the right point of the orbit and stellar cycle, the star’s chromosphere brightens.

A Falcon 9 rocket topped with the 15,400-pound (7,000 kilograms) SXM-11 spacecraft is scheduled to lift off from Cape Canaveral Space Force Station tonight during a four-hour window that opens at 10:25 p.m. EDT (0225 GMT on June 29).

Nvidia is hiring a Principal Systems Software Architect for SPACE-1, its orbital data center module built on Vera Rubin, a sign its space-AI ambitions are moving from concept toward development. The driver is the AI power bottleneck on the ground.

It’s sometimes easy to overlook the fact that the International Space Station (ISS) is a giant lab where scientists study everything from biology to physics—but in space. This extraordinary resource makes extraordinary research possible—like creating a fifth state of matter in space.

A SpaceX Falcon 9 rocket carrying 24 Starlink satellites lifted off from Vandenberg Space Force Base in California on Sunday, June 28, 2026.

The photo, taken during the X-37B’s seventh mission, shows Earth from High-Elliptical Orbit. On Feb. 20, 2025, the Secretary of the Air Force Public Affairs uploaded on the DVIDS website, what is believed to be the first-ever in-orbit officially released ...
