Using a radio telescope scanning the entire planet, scientists recorded the 'dancing jets' erupting from a black hole 7,000 light–years from Earth. These jets unleash power equivalent to the output of 10,000 suns and travel at 150,000 km per second – nearly half the speed of light. However, the terrifying fountains of superheated matter only use about 10 per cent of the energy gobbled up by the black hole as it feeds. These incredible discoveries come from a binary system called Cygnus X–1, which is home to a supermassive star and a black hole.
