Sgr A* is one of very few black holes where we can actually witness the process
-Q. Daniel Wang
The giant black hole at the centre of the Milky Way appears to be on a severe diet. Scientists have now taken a major step towards understanding why - with new data providing insights into the reason behind the lack of radiation from material near some black holes.
Latest research shows the black hole ejecting matter it has funneled towards its ‘event horizon’ – or point of no return – because it’s too hot and spread out, with less than 1% of possible matter in its gravitational pull actually being consumed.
The new findings, published in the journal Science, are the result of one of the biggest observing campaigns ever performed by NASA’s Chandra X-ray Observatory.
