Yes, you read the title of this blog correctly! Astronomers have given this cool and non-technical name to an extremely rare new class of galaxies - Green Bean Galaxies. These galaxies are very distant and the entire galaxy glows from the light of the massive black hole at their center.
There are only 16 of these galaxies known at present after scanning through a billion galaxies. Ionized oxygen makes the color of these galaxies but the fact that the ENTIRE galaxy is aglow and not just the center as with other galaxies with a supermassive black hole at the center is really special.
