The Hubble telescope has been looking for black holes and studying in particular the supermassive black hole in the most massive galaxy (M87).
The supermassive black hole is not in the position that it is supposed to be in which is odd as supermassive black holes are supposed to be at the centre of galaxies. A possible reason why this black hole is not in the correct place could be that two other supermassive black holes came together to form this one.
M87 is 55 million light years away and is very popular amongst astronomers and this will make it even more interesting.
