Here’s what the inside of our galaxy, which has a supermassive black hole in the chewy center, looks like. This galaxy, this galaxy, and this galaxy have black holes in the center. We can observe over 200 billion galaxies from Earth (with technology) and there are thought to be 300 billion more in our “observable” universe. Most, if not all galaxies have supermassive black holes in their centers.
This is an amazing version of a great song by Radiohead called Black Star.
