8:53

NGC 34 (also known as NGC 17) is a chaotic-looking galaxy that formed from two smaller galaxies merging together, and it is a place where astronomers have easily found lots of stars forming in a starburst but where they have had difficulty concluding whether the galaxy also contains a supermassive black hole.…
