APOD 3.7

Today's APOD is from February 23rd and is VERY cool.

This is an image of Saturn but notice how it is missing its rings? The blue line you see is actually the rings. This image was taken by the robot Cassini. In reality, those rings are only as thick as a razor blade. This was first noticed by Galileo in 1612 and he was really worried and confused by the phenomenon. The robot that took the picture is actually in Saturn's orbit and this photo was archived by Fernando Garcia Navarro. I chose this photo because I never had any idea that the rings were THIS thin and it is truly amazing.
