The habitable zone is the not-too-hot, not-too-cold region around a star where liquid water can exist.

Lava worlds. Hot Jupiters. Earth 2.0 candidates. Here's a rundown of some notable exoplanets.

Some methods almost sound like science fiction: Using gravity as a magnifying glass, watching stars wobble at turtle-like speeds, and searching for tiny dips in starlight.

Remember the amazing photo of Saturn's north pole that I posted yesterday? Now, thanks to an amateur image processor, it moves, and the motions of the individual clouds within the belts are mesmerizing.

A recent series of ring images by the Cassini spacecraft reveal Saturn's tiny moon Daphnis cruising through the Keeler Gap.

The apparently simple device of running Cassini images together like a flipbook makes for a dramatic movie, especially with the help of well-timed musical cues.

Cassini performed its last of three close encounters with Enceladus for 2012 two days ago, and followed the flyby with some spectacular images of Dione.

Clearly, this is Saturn, and its rings, and if you look closer you can see a tiny circle, on top of the rings, which is Mimas, and two stars in the background. It should look weird to you that while the rings are bright, Mimas is a black dot. What is happening here? Nearly everything in this picture is lit by light that has not arrived directly from the Sun.
