This is getting cooler than I really thought it would. Check out this incredibly ugly little Saturnian moon, Iapetus.
JPL has a lot more pics. It’s getting really close now. However, unlike Io or Europa, the closer it gets to Iapetus, the uglier it gets. This poor little moon has obviously been battered hard by meteor strikes. It’s little spine circling the moon is the source of a lot of speculation. However, my completely uneducated guess is those two really large strikes on the same side have something to do with it. If you’ve ever squeezed a pingpong ball really hard you’d know what I’m referring to. That’s just a guess tho. I’ll leave the hard science up to those who get paid to do it. I’m in the boat of those people who just LOVE seeing this for no other reason than curiosity.
