Astronomers have observed two black holes in nearby galaxies devouring their companion stars at an extremely high rate, and spitting out matter at a quarter the speed of light.
Researchers have successfully simulated how a ring-shaped black hole could cause general relativity to break down: assuming the universe contains at least five dimensions, that is.
New window on the universe is opened with the observation of gravitational waves – ripples in spacetime – caused by the collision of two black holes.
An international team of astronomers has found a pulsating, dead star beaming with the energy of about 10 million suns. This is the brightest pulsar – a dense stellar remnant left over from a supernova explosion – ever recorded.
The discovery of three closely orbiting supermassive black holes in a galaxy more than four billion light years away could help astronomers in the search for gravitational waves: the ‘ripples in spacetime’ predicted by Einstein.
European Space Agency announces broad plan for major space science missions over the next two decades, with Cambridge’s Institute of Astronomy involved at the highest levels.
