Space Porn

IO9, one of the Gawker group of blogs, is devoted to science fiction and stuff people who like science fiction might like. I've never really done more than glance at the site, and was a bit turned off by how much it seemed to concentrate on sci-fi movies and television. Don't we hear enough about them?

But I just discovered a feature they have that I really like: Space Porn. This seems to be their term for really cool astronomical images and photos. Like this image of dunes on Mars:



Or this image of Saturn eclipsing the sun (taken by the Cassini-Huygens space probe):



Cool, huh?
