NASA's Kepler telescope has discovered a veritable bounty of alien planets, but none of them have been quite like Earth -- until now. Today, the agency announced that Kepler-186f is the first confirmed Earth-sized planet in the habitable zone of another star. In other words, it's the right size an

Scientists have long thought that the dwarf planet Ceres might hold some form of water, but they've only had indirect evidence at best -- until today, that is. An ESA-led team has used signal fluctiations to confirm that the asteroid belt planetoid is spewing water vapor from two points on its su

Astronomers have a good day when they detect one planet inside a star system's habitable zone. A mostly European team of researchers must be giddy, then, as it just found three of those ideally located planets around Gliese 667C. The group has combined existing observations from the ESO's Very Lar

NASA's Kepler telescope is permanently on the lookout for celestial objects of interest, and its latest discovery is a small one. A small planet, to be exact -- in fact, the smallest its encountered during its search. Kepler-37b is a tad larger than our heavenly dance partner, the Moon, and whizze

The Cassini space probe has collected quite a few memories of Saturn in its eight years, swinging by the planet's moons and even listening to lighting storms. Even so, we're being treated to an uncommon sight today: the dark side of Saturn. A newly processed set of 60 images, originally taken in O
