A new SpaceX effort to provide space traffic coordination services has attracted attention and praise in part because of the conditions it places on users.

The International Space Station orbits Earth about 16 times each day and goes over Middle Tennessee about once each day, but ...

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

Researchers at The University of Manchester have developed a new way to design Earth-observation satellite missions that could help protect the space environment while continuing to deliver vital data ...

The planets are visible throughout February, "but they’ll be lined up best toward the end of the month,” NASA says.

New research suggests that the heart of the Milky Way may be dominated by a dense clump of dark matter rather than the ...
