How Do Space Pictures Get So Pretty?
Photoshop, of course.
Space pictures weren't always so pretty. David Malin, a scientist at a telescope facility in Australia, did the pioneering work in color visualization more than 20 years ago.

The modern master of the field is Zoltan Levay, who works on images sent down from the Hubble.
