M106 (NGC 4258) in Canes Venatic
M106 (Messier 106 also known as NGC 4258) is a spiral galaxy in the constellation Canes Venatici, discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth. It is also a Seyfert II galaxy, which means that due to x‑rays and unusual emission lines detected, it is suspected that part of the galaxy is falling into a supermassive black hole in the center. The small galaxy to the right of M106 is NGC 4248 shining at 12.5 mag.
