|Some times when you have not done something in a while you get rusty. Here is an example. I was surprised by a clear night and did not have a target ready so I went to my databases and selected IC 922 after misreading it as 18' x 18' (arcminutes) vs. what it actual said 18" x 18" (arcseconds); a factor of 60! The small arrow points to IC 922.
It is a faint (15.2 Mag) elliptical galaxy that is 935 Million light years distant.
Actually, I love these kind of pictures. If you look at them carefully, you can see hundreds of galaxies in them. And a lot of them are at similar distances.
|Here is a much more conventional galaxy, NGC 4725. It is a mere 55 Million light years away in the constellation Coma Berenices. It's size is a more respectable 10.7' x 7.6'|
|The center galaxy in this image is the super large elliptical galaxy NGC 4889 but this image is really the center of the Coma Cluster of Galaxies. If you pass your mouse over the image, a map of the galaxies will be displayed (The larger galaxies will have their designations displayed.) Astronomer Fritz Zwicky used the Viral Theorem on this group of galaxies to infer the more mass than what was visible. He coined the term Dark Matter to describe it in 1933.||Here is an edge on spiral NGC 4565 also in Coma Berenices. It's distance is 56 Milion Light Years. This spiral shows a great deal of dust on it's edge.|
