That was unexpected.

A particular black hole is so enormous it changes what we thought we understood about some galaxies.  It actually outgrew the host galaxy at a rapid pace which has astronomers scratching their heads.  Usually the number of stars is positively correlated with the size of the black hole.

Here is a bit more information on what they found.  The first spotting happened in 2015 like so many astronomical anomolies:

The discovery of the black hole was originally announced in July this year. It was observed with the NASA Hubble Space Telescope, in the Sloan Digital Sky Survey and then by ESA’s XMM-Newton and NASA’s Chandra X-ray Observatory.

Now follow-up observations by Benny Trakhtenbrot, from ETH Zurich’s Institute for Astronomy, and an international team of astrophysicists, using the 10 metre Keck telescope in Hawaii has thrown up some surprising results.

We’re looking forward to finding out more about this disruptive discovery.  And we will be posting details as they come in..

And this is a video on super massive black holes in general which we hope you enjoy.
