Black hole surprises with “hiccups” – “We thought we knew a lot”. Black hole makes its host galaxy become significantly brighter.
It is orbited by a smaller black hole that fights its way through the accretion disk and releases gas clouds in the process. The object was torn apart by the black hole's gravity - a process astronomers call "spaghettification". The black hole devoured the stellar remnants for four months, while the second black hole moved through the disk regularly.
