If engineers can't find a fix, the failure could mean an end to the $600 million mission's search, although the space agency wasn't ready to call it quits Wednesday. The telescope has di...

(AP) — Now's your chance to see the comet that passed within 100 million miles of Earth last week. Twilight on Tuesday will provide the best photo op for the comet called Pan-STARRS. It will be visible in the Northern Hemisphere just above the western horizon — right next to a crescent moon. California astronomer Tony Phillips said th...

(AP) — A recently discovered comet is closer than it's ever been to Earth, and stargazers in the Northern Hemisphere finally get to see it. Called Pan-STARRS, the comet passed within 100 million miles of Earth on Tuesday, its closest approach in its first-ever cruise through the inner solar system. The ice ball will get even nearer th...

But hunters for life in the universe will need to poke elsewhere. The new world orbits too close to its sun-like star and is too sizzling to support life. Its surface temperature is an estimated 700 de...

That's more than two Earth-size planets for every person on the globe. Just how many are located in the sweet spot where water could exist is "simply too early to call," said Francois Fressin of the Harvard-Smithsonian Center...
