In the very center of our own Milky Way galaxy, a supermassive black hole surrounded by a cluster of stars sits and quietly spins. Worry not, this black hole does not pose a threat to Earth and our Solar System, and we will likely never have to worry about it! The photo may be recognizeable, since it broke news and was publicly released in 2022 for the first time. Higher quality renditions have come out, but this is the most famous photo of the black hole sitting in the center of our own galaxy. The orange "disc" around the black mass is the accretion disc! Black holes have a tendency to accumulate debris and spin it around, the friction causing it to heat up and give off light. Sagittarius A* (Shortened as Srg A*), was first discovered in 1974 by Robert Brown and Bruce Balick.
