M106 rework

M106 is at a distance of about 22 to 25 million light-years away from Earth
Messier 106 (also known as NGC 4258) is a spiral galaxy about in the constellation Canes Venatici. It was discovered by Pierre Mechain in 1781.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.[7] NGC 4217 is a possible companion galaxy of Messier 106.[6]
