You probably already knew today is Black Hole Friday. To celebrate, NASA and other agencies have been posting black hole stuff. Like the above, an artist's conception of a black hole five times the mass of the one at our galaxy's center, in a superdense galaxy 1/500th the diameter of our own, the M60-UCD1 dwarf galaxy.
As NASA writes about the above image, "If you lived inside this dwarf galaxy, the night sky would dazzle with at least 1 million stars visible to the naked eye. Our nighttime sky as seen from Earth's surface shows 4,000 stars."
And here's a gorgeous image of NGC 1313, or the Topsy Turvy galaxy. The two magenta spots in the galaxy represent two black holes.
The "slumbering" black hole at the center of the nearby sculptor galaxy.

Artist's illustration in which "turbulent winds of gas swirl around a black hole. Some of the gas is spiraling inward toward the black hole, but another part is blown away."
