Centaurus A is a galaxy in the Centaurus Constellation that was first discovered in 1826 by Scottish astronomer James Dunlop from Australia. It is one of the closest radio galaxies to Earth. Therefore, its active galactic nucleus has been researched extensively over the years. It is the fifth brightest galaxy, visible only from the southern hemisphere and low northern latitudes.
Centaurus A is located more than 12 million light years away from Earth. It contains a supermassive black hole having 55 million times the mass of sun. The black hole ejects a jet of matter that acts as a bright source of radio light.
