Ya know, for a tiny ball of ice, Saturn’s moon Enceladus really knows how to pose for a picture<\/a>:<\/p>

Cassini snapped this shot from 34,000 km (20,000 miles) away, looking down on the northern hemisphere of Enceladus. Peeking just over the edge is a slice of Saturn’s rings, too. <\/p>

Most of the action on Enceladus is at the south pole, where geysers of water are erupting. But up at the other end of the 500 km wide moon — for comparison, Colorado is 600<\/em> km across — it’s still pretty nifty. The reflective, icy surface is saturated with craters, including that interesting triple smackdown on the left. Something must have broken apart as it hit… though I’ll note the two big craters are elongated, indicating a very shallow angle of impact, while the third smaller one is round. It may only coincidentally line up with the other two. If that’s the case, maybe a binary asteroid hit here long, long ago.<\/p>

Cracks snake their way across the surface too. Enceladus certainly has liquid water under ...<\/p>
