This image was obtained as part of the Coma Cluster Treasury Survey, a deep imaging survey of one of the nearest rich clusters of galaxies, Abell 1656 (Coma Cluster).

It reveals both the relatively calm outskirts and extremely bright core of the galaxy PGC 83677.

PGC 83677 is a lenticular galaxy — a galaxy type that sits between the more familiar elliptical and spiral varieties in the Hubble sequence.

Also known as 2MASX J12571076+2724177 and SDSS J125710.75+272417.6, this galaxy lies roughly 300 million light-years away from Earth in the constellation of Coma Berenices.

PGC 83677 is also a Seyfert I galaxy. Its luminous heart is a source of high-energy X-rays and ultraviolet light, causing astronomers to suspect that it hosts a monstrous black hole.

This image of PGC 83677 was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS).

It is based on data obtained through two filters: the blue filter F475W and the near-infrared filter F814W.

The color results from assigning different hues to each monochromatic image associated with an individual filter.
