APOD 1.2

NGC 4911: Spiral Diving into a dense Cluster

NGC 4911 is, in a way, very much like our own galaxy, in that it is a spiral galaxy with many rotating arms and a bright central core.  At the same time, we can see its future based on how most of 4911's neighboring galaxies have turned out.(yellowish elliptical galaxies), we can see this process happening (there are 3 faints rings extending from the galaxy where the neighboring galaxies are pulling 4911 apart), and we can see that 4911 is nothing but a very small part of the big picture (4911 is being drawn into the Coma Cluster of galaxies, which has over 1,000 galaxies inside of it).

P.S. This APOD was supposed to be for the week of September 10th.
