Black Hole

A black hole, ejecting material at close to the speed of light, has been observed using e-MERLIN, the UK's radio telescope array based at Jodrell Bank Observatory. A research team based at Oxford University used e-MERLIN, as well as the VLA and MeerKAT telescopes based in the US and South…
