At first glance it looks like a bunch of noise—grainy and empty. The super geeks that read my blog (are you out there?) will recognize this photo as The Pale Blue Dot, which was selected by as one of the top ten space science photos of all time.

That very small bluish dot is Earth. From Wikipedia:

The Pale Blue Dot is a photograph of planet Earth taken in 1990 by Voyager 1 from a record distance, showing it against the vastness of space.
