Here is
spiral galaxy NGC 4845. It's over 65 million light years away in the constellation Virgo. There's notable spiral structure, and a dusty disk surrounding a bright central bulge.
At the center of the galaxy is a supermassive black hole that acts on the innermost stars. They're travelling around the galactic center must faster than they would be with no black hole. Judging by the speed of these stars, the black hole has a mass equal to hundreds of thousands of stars the mass of our Sun.
