A Different Sort of Glob


Here is a globular cluster. We have already seen M13 a few times, but this one is M2. It is somewhat more faint than M13, but it is just as spectacular. This cluster is about 37,000 light years away and is almost 200 light years across. There are nearly 150,000 stars in the cluster.

This second picture is the result of playing with the levels in the picture to get a more accurate representation of the colors. I have yet to figure out how to do it without completely blowing out the center.
