Black hole pictured for first time
Black hole pictured for first time — in spectacular detail
Astronomers have finally glimpsed the blackness of a black hole. By stringing together a global network of radio telescopes, they have for the first time produced a picture of an event horizon — a black hole’s perilous edge — against a backdrop of swirling light.
“We have seen the gates of hell at the end of space and time,” said astrophysicist Heino Falcke of Radboud University in Nijmegen, the Netherlands, at a press conference in Brussels. “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.”
The images — of a glowing, ring-like structure — show the supermassive black hole at the centre of the galaxy M87, which is around 16 megaparsecs (55 million light years) away and 6.5 billion times the mass of the Sun. They reveal, in greater detail than ever before, the event horizon — the surface beyond which gravity is so strong that nothing that crosses it, even light, can ever climb back out.
