In April, the Event Horizon Telescope network announced that it had obtained the first image of a black hole — at the centre of the galaxy M87. (EHT Collaboration)
In April, the first-ever image of a black hole
This golden doughnut is the first image ever of the event horizon that surrounds a black hole — in this case, the supermassive black hole at the centre of a nearby galaxy called M87. The image offered a spectacular confirmation of the existence of black holes, first deduced from Albert Einstein’s general theory of relativity 100 years ago. Black holes are widely accepted to exist, but have never before been directly observed. Astronomers created the new image by processing radio-wave observations invisible to the human eye.
“We have seen the gates of hell at the end of space and time,” said astrophysicist Heino Falck. “What you’re looking at is a ring of fire created by the deformation of space-time. Light goes around, and looks like a circle.”
