We need your eyes and brain to learn about distant galaxies. There are amazing things we could discover if you help us look — like extremely rare black holes with strange “intermediate” mass. Most black holes are either small (roughly the mass of 10-20 Suns) or supermassive (the mass of a million or billion Suns). But sometimes we find a black hole that’s somewhere in the middle range, maybe 100-100,000 solar masses, and those could tell us a lot about black hole evolution. Less than a dozen of these special black holes have been observed in the entire universe, but you could help us find more.
