Description

This is Messier 106, an intermediate spiral galaxy in Canes Venatici about 23.5 million light years away. This galaxy is unusual in that its active central black hole—36 million times the mass of the sun and nine times the mass of the Milky Way’s central black hole—may primarily account for the galaxy’s odd shape. The usual reason for this kind of galactic misshapenness is some kind of gravitational interaction with another galaxy in the past. But apparently not in this case—at least, not directly.

An active galactic nucleus containing a supermassive black hole like this one usually emits powerful jets of accelerated particles at right angles to the galactic disk. But this nucleus seems to be spewing its jets into the spiral arms of the galaxy, causing the odd shape we now see. No one really knows why. Perhaps, after all, it’s because of some primordial gravitational interaction with another galaxy that tilted the nucleus on its side.
