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.
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.
Astronomers have discovered enormous smooth shapes that look like vapour trails in a gigantic galaxy cluster. These ‘arms’ span half a million light years and provide researchers with clues to a billion years of collisions within the “giant cosmic train wreck” of the Coma cluster.
Astronomers working with NASA's Chandra X-ray Observatory have seen the giant black hole Sagittarius A* rejecting its ‘food’ of vast gas clouds as they aren’t sufficiently cool enough for it to swallow.
A long-sought “echo” of light that promises to reveal more about supersized black holes in distant galaxies has been identified by an international team of astronomers.
