Messier 106


Messier 106 also known as NGC 4258 is an intermediate spiral galaxy about 22 to 25 million light-years away from Earth. It is also a Seyfert II galaxy. X-rays and unusual emission lines have been detected coming from M106, leading astronomers to suspect that part of the galaxy is falling into a supermassive black hole in the center. A Type II supernova was observed in this galaxy in May, 2014. A Type II supernova is caused by a the rapid collapse and subsequent violent explosion of a massive star.
