M 106 and NGC 4248

Messier 106 (or NGC 4258) is a spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 25 million light-years away from Earth. It is also a Seyfert 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 below is NGC 4248, which is believed to be much further away.
