Every time I think Cassini can't possibly send back a more dramatic image from Saturn, it takes my preconceived notions and crushes them to dust.
Oh. My. That shows the moons Titan (in the background) and Rhea, the two largest of the gazillions of moons circling the ringed planet. Titan has an atmosphere, which is why it looks fuzzy. This picture is crazy amazing! Rhea looks like it's about to smash into Titan -- if you're curious, this is what my nightmares look like -- but in fact they're very far apart. Rhea was about 1.1 million kilometers (680,000 miles) away from Cassini when this was taken, and Titan was more than twice that. So they were actually separated by over a million kilometers, about three times the distance of the Moon from the Earth! Cassini used the narrow-angle camera (essentially a big telescope) to get this shot, so it ...
