            | COMMENTS: 
 | Not
the prettiest image of M51 ever taken, but I wanted to capture
Supernova 2011dh (pointed out with the arrow above).  The
supernova was spotted about 5 days before this image was taken. It's a
Type 2 supernova, which is caused by the explosion of a single massive
star.
