It took over a decade and millions of images but the SDSS (Sloan Digital Sky Survey III) has released a remarkably detailed image of the night sky. The image has over a trillion pixels. If you wanted to see it in its full resolution, you'd need half a million HD TVs.
The image is free for everyone to use. Now, you can comb through the image looking for distant quasars. You probably won't, but you can.
