When the Kepler space telescope malfunctioned last spring, it looked as though its incredibly successful planet-hunting mission might be over—and NASA made that sad fact official a few months later.

The best time to hunt for Ursid meteors is from the evening of Dec. 21 straight through to dawn on Dec. 22. The shower's peak ...

NASA plans to launch a mini satellite into Earth's orbit that could revolutionize astronomy as we know it.

Look up at the sky on a clear night, and you’ll see thousands of stars – about 6,000 or so. But that’s only a tiny fraction of all the stars out there. The rest are too far away for us to see them.
