About this Image

Subject M106, with possible companion NGC 4248 spiral in lower left of image
Data NED database entry
Description M106 is a galaxy located in the constellation of Canes Venatici (the hunting dogs). At a distance of 29 million light years it is one of the closest Seyfert type galaxies. Seyferts are a class of galaxies with intensely bright cores - their radiation is thought to be generated by gas infalling onto the accretion disk of their central supermassive black hole. Seyferts could be considered as a "missing link" between quasars and the generally quiescent central blackholes found in galaxies in the current epoch.
