A few months ago, there was a project named Galaxy Zoo, which basically got people to classify galaxies. This time, they are doing Galaxy Zoo 2, which is the same, except it has brighter and larger galaxies, and you classify how rounded they are, whether they have features, how tight the spirals are, etc. They have found some interesting stuffs through it. If you love astronomy pictures, or science in general, you should check it out.
Oh, and it also has its own blog.
