Three scientists have won the 2020 Nobel prize in physics for their work on black hole formation and the discovery of a supermassive black hole at the centre of our galaxy.

Black holes may merge with light of a trillion suns, scientists say

When black holes collide, the ensuing cosmic drama was assumed to play out under the cloak of darkness, given that both objects are invisible. But now astronomers believe they have made the first optical observations of such a merger, marked by a blaze of light a trillion times brighter than the sun.
