Enceladus

Here are some fantastic shots of Enceladus, one of Saturn's moons, made by NASA's Cassini as it whizzed by at 14 km/second (over 30,000 mph) and as close as 52 km off the surface. Enceladus is pretty tiny but it is covered in ice and contains a cryovolcano that is like a regular volcano except it shoots out water and gasses, in this case 500 km in the air. No one is really sure what's causing it but it's still pretty amazing.

Uh oh, dinosaurs and moon shots...it's becoming (even more) nerdy in here. Hopefully I'll have what I think is a pretty funny post about this weekend up soon...
