Scientists on Wednesday revealed the first image ever made of a black hole.
 
科学家周三公布了首张黑洞照片。
 
 
Assembling data gathered by eight radio telescopes around the world, astronomers1 created the picture showing the violent neighborhood around a supermassive black hole, the light-sucking monsters of the universe theorized by Einstein more than a century ago and confirmed by observations for decades.
 
It looked like a flaming orange, yellow and black ring.
 
"We have seen what we thought was unseeable. We have seen and taken a picture of a black hole. Here it is," said Sheperd Doeleman of Harvard.
 
Jessica Dempsey, a co-discoverer and deputy director of the East Asian Observatory2 in Hawaii, said it reminded her of the powerful flaming Eye of Sauron from the "Lord of the Rings" trilogy.
 
Unlike smaller black holes that come from collapsed3 stars, supermassive black holes are mysterious in origin. Situated4 at the center of most galaxies5, including ours, they are so dense6 that nothing, not even light, can escape their gravitational pull. This one's "event horizon" - the point of no return around it, where light and matter begin to fall inexorably into the abyss - is as big as our entire solar system.
