Description:
Messier 106 (also known as 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 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. NGC 4217 is a possible companion galaxy
of Messier 106.(Wikipedia)
