Radio images of the sky have revealed hundreds of “baby” and supermassive black holes in distant galaxies, with the galaxies’ light bouncing around in unexpected ways.
Galaxies are vast cosmic bodies, tens of thousands of light years in size, made up of gas, dust, and stars (like our Sun).
Given their size, you’d expect the amount of light emitted from galaxies would change slowly and steadily, over timescales far beyond a person’s lifetime.
But our research, published in the Monthly Notices of the Royal Astronomical Society, found a surprising population of galaxies whose light changes much more quickly, in just a matter of years.

they're always misbehaving. I blame the larger black holes. They don't set a very good example for the youngsters, hogging all the light, sucking everything in their path right into their gaping maws. The toddler black holes don't fall far from the super-massive black hole trees. NOW GET OFF MY GRASS!
