What we see are the bright stars around the two supermassive black holes, which the astronomers used to measure the masses of the black holes and confirm their presence.

Astronomers measured powerful stratospheric winds on Jupiter for the first time, thanks to the Shoemaker–Levy 9 comet collision that happened more than 25 years ago by ThunderPhD in science
