Black Hole

From a fuzzy, fiery doughnut-shaped object to a slim circle - scientists say AI has helped us 'really see' a black hole 'for the first time'.

Dubbed Sagittarius A*, astronomers have revealed that the black hole is four million times the mass of our own sun.

Londoners posted their images on Twitter of what one described as a 'creepy cloud' but which experts have identified as Asperitas.
