Astronomers Study Two Million Light Year ‘Extragalactic Afterburner’

Blasting over two million lights years from the centre of a distant galaxy is a supersonic jet of material that looks strikingly similar to the afterburner flow of a fighter jet, except in this case the jet engine is a supermassive black hole and the jet material is moving at nearly the speed of light.

Research published over the weekend in the Astrophysical Journal Letters shows the galaxy-scale jet to have bright and dark regions, similar to the phenomenon in an afterburner exhaust called ‘shock diamonds.’

“One intriguing possibility is that the pattern we see in this cosmic jet is produced in the same way as the pattern in the exhaust from fighter jet engines,” said Dr Leith Godfrey, from the Curtin University node of The International Centre for Radio Astronomy Research.
