One of my favorite books is Hydrogen: The Essential Element by John S. Rigden which coincidentally I'm reading again. Rigden provides the background that explains why this mysterious green glob is so interesting and exciting.
But the reason I'm posting the story is because of this:
The blob was discovered by elementary school teacher Hanny van Arkel, who was 24 at the time, as part of a worldwide Galaxy Zoo project where everyday people can look at archived star photographs to catalog new objects.I find that just so very rewarding. Imagine how thrilled this young woman feels for having discovered something so incredibly interesting and something which might lead to better understanding of our universe.
Van Arkel said when she first saw the odd object in 2007 it appeared blue and smaller. The Hubble photo provides a clear picture and better explanation for what is happening around the blob.
