Relativistic jets from the supermassive black hole in Centaurus A extend perpendicularly from the galaxy.
The first direct observation of gravitational waves was made on 14 September 2015 and was announced by the LIGO and Virgo collaborations on 11 February 2016. Previously, gravitational waves had been i
