The world got a glimpse（一瞥）of one of the greatest mysteries of our universe（宇宙）on April 10. That's when the first image of a black hole was shown to the public. The picture was created by a network of eight radio telescopes（射电望远镜）.

“We have seen what we thought was unseeable ,"says Shep Doeleman. He led the effort to create the image.

The black hole is at the center of galaxy（星系）named Messier 87,some 55 million light-years from the earth，and is 6.5 billion times the mass of the sun.

The image shows the gas，dust，and stars that move around the black hole before disappearing into it. It does not truly show the black hole，because not even light can escape its gravity. Black holes, like vacuums, suck（吸）in everything that gets too close.
