This blog post is mainly for James. :) I'm sure he's already seen the images, however I really enjoyed them and felt they were blog worthy: Bad Astronomy Blog » The Top Ten Astronomy Images of 2006
I changed my desktop background to the image at the very bottom (the #1 astronomical image of 2006). It's amazing how small Earth is in the image. The post states that Cassini took the image and was one billion miles from us when it took the image... yeah... 1,000,000,000 miles away. Man!
