Last week I gave you a glimpse of how I created a faux galaxy from an otherwise crappy photo. This is how the real galaxies are photographed. The Hubble Telescope (and other imaging means) takes over 1400 stills of a single galaxy, over the course of many days. All these images are then cleaned up and processed in photoshop to make the pretty pictures you see in science textbooks. I guess even heavenly bodies aren’t immune to a little airbrushing. Video after the jump.
