blackholes
The object is a quasar with a black hole at its heart growing so fast that it swallows the equivalent of a sun a day, astronomers say. The record-breaking quasar shines 500 trillion times brighter than our sun. The black hole powering this distant quasar is more than 17 billion times more immense than our sun, an Australian-led team reported Monday in the journal Nature Astronomy. While the quasar resembles a mere dot in images, scientists envision a ferocious place. The rotating disk around the quasar's black hole — the luminous swirling gas and other matter from gobbled-up stars — is like a ...

By The Conversation One of the most intriguing predictions of Einstein’s general theory of relativity is the existence of black holes: astronomical objects with gravitational fields so strong that not even light can escape them. When a sufficiently massive star runs out of fuel, it explodes and the remaining core collapses, leading to the formation of a stellar black hole (ranging from 3 to 100 solar masses). Supermassive black holes also exist in the centre of most galaxies. These are the largest type of black hole, containing between one hundred thousand and ten billion times more mass than ...
