Astronomy Events for 2011

Cosmology
Galaxy Zoo	galaxyzoo.org You can help astronomers classify galaxies. This is the third version of this project. As of early 2010 it is just getting started using images from the Hubble telescope. The images are of distant galaxies and are not the bright, colorful, clear images you see in coffee table books about the Hubble telescope. The human eye/brain is better than computers at classifying the images. The volunteers who used the first two versions of this site made tens of millions of classifications of types of galaxies and characteristics of the galaxies.
