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.
Several missions this year are seeking out life on the red planet. But would we recognize extraterrestrials if we found them?
Discovery has major implications for hunt for alien life on the red planet as it means any evidence is likely to be buried deep underground
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.
Object found in HR 6819 system is the closest to Earth yet known – and is unusually dark
Detailed image taken by Event Horizon Telescope of black hole 5bn light years away
First observations from Inouye telescope bring previously hazy star into sharp focus.
The striking images reveal a surprising level of structure hidden within the churning plasma exterior, bringing a previously hazy impression of the sun’s patchwork surface sharply into focus for the first time.
Objects raise hopes of scientists managing to track ‘blobs’ being swallowed by black hole
A number of bizarre shape-shifting objects have been discovered close to the supermassive black hole at the centre of the Milky Way.
The blobs are thought to be giant stars that spend part of their orbits so close to the black hole that they get stretched out like bubble gum before returning to a compact, roughly spherical form.
Scientists say Milky Way’s Sagittarius A* has been more active in recent months. Unseeable and inescapable, black holes already rank among the more sinister phenomena out in the cosmos. So it may come as disconcerting news that the supermassive black hole at the centre of the Milky Way appears to be growing hungrier.
