This is one of the first studied active (Seyfert) galaxies and it is thought to harbor a pair of black holes whose combined mass is around 50 million Suns—more than 10 times our own Milky Way's central monster (at 4 million or so). Be certain to look up Hubble Space Telescope (HST) images of the central region of this galaxy and compare with this full color image in order to better understand all of the things this galaxy offers.

Also check out the fine tidal tails of two other galaxies with streams of stars coming out of them. The one towards the top appears to come from another compact spiral in the background- but is probably a chance alignment. A fainter one associated with another satellite galaxy is towards the bottom.
