This is a galaxy

Much like Dr. Plait, the Bad Astronomer, I don't really think I can add a whole lot to this. Like him, you absolutely must watch it in HD and full screen though.  Go ahead, it's only 90 seconds, and you may learn something, or at least be amazed at the things we are able to figure out. Aren't we clever considering we're just apes on an insignificant planet in a totally insignificant part of the universe.
