If you've got some free time, decent eyes, and want something interesting to do, why not head on over to Galaxy Zoo and help out science?
Galaxy Zoo is a massive project, utilizing the fantabulousness of the internet to assist researchers in classifying over a million galaxies from the Sloan Digital Sky Survey. They show you how to identify the different types of galaxies, common optical illusions created by stars, satellite reflections, and what to look for if two galaxies are merging.
It's contributing to science, people!
Plus... the pictures are so pretty!
Admittedly, some of them aren't so pretty and it's hard to tell through the blur what you're looking at, but some of them... well... they're gorgeous....
This one I stole from the tutorial page, but you run across some of them yourself, too.
Go check it out, contribute a bit, and see some pretty shiny things way off in space!
*Edit: I fixed the link, folks. Many apologies for the bad link, if you tried it before... well, it works better now. My bad...
