Messier 106 : Our member of galaxies partner

Messier 106 : Our member of galaxies The universe is a vast expanse filled with wonders beyond our imagination. Among these wonders are galaxies, vast collections of stars, gas, dust, and dark matter held together by gravity. One such galaxy that captivates astronomers and stargazers alike is Messier 106, a stunning spiral galaxy located in the constellation Canes Venatici. Unveiling Messier 106: Discovered by the French astronomer Pierre Méchain in 1781, Messier 106, also known as M106 or NGC 4258, is a member of the relatively nearby Virgo Supercluster, which contains our own Milky Way galaxy. It lies approximately 22 to 25 million light-years away from Earth, making it a relatively close neighbor in astronomical terms. Messier 106 is classified as a Seyfert II galaxy, which means it has an active nucleus that emits strong radiation across the electromagnetic spectrum. This activity is believed to be fueled by a supermassive black hole at its center, which is devouring surrounding ma...
