Image notes |
NGC 6166 is
the large type E galaxy at the center of the image.
It is the dominant galaxy within the Hercules cluster
Abell 2199. The core of
this galaxy is split into three distinct knots surrounding
an active galactic nuclei containing an estimated ~10^9
solar masses (Di Matteo, et.al., 2001).
Abell 2199 is at the northern end of the extensive Hercules
Cluster of Galaxies found
here. The "core" of
the cluster is an astounding 22 degrees to the south and is
designated as Abell 2151. The shear number of galaxies
found along this corridor is what forms the backbone of the
Hercules Supercluster. |
