Spiral Galaxy M106 in Canes Venatici Post-it Notes

Galaxies, Stars and Nebulae series 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. image code: m106cv Image credit: NASA, ESA, the Hubble Heritage Team (STScI/AURA), and R.
