Supermassive black hole discovery from deep in space

A statement from NASA:

“An international team of astronomers using the NASA/ESA Hubble Space Telescope have uncovered a supermassive black hole that has been propelled out of the centre of the distant galaxy 3C186. The black hole was most likely ejected by the power of gravitational waves. This is the first time that astronomers found a supermassive black hole at such a large distance from its host galaxy centre.”

There are multiple theories.. perhaps two black holes combining..
But what is amazing: The galaxy, 8 billion light years away (meaning 8 billion light years in the past), is featuring something amazing.. a discovery to change science–something that seemingly happens daily.
At the speed the black hole is traveling: It could be from Earth to the moon in three minutes..
