First image ever made of a black hole revealed   

WASHINGTON (AP) -- Humanity got its first glimpse of the cosmic place of no return: a black hole.

In a breakthrough that led to talk of a Nobel Prize, an international team of scientists on April 10 released the first image ever made of a black hole, revealing a bright doughnut- shaped object in a galaxy 55 million light-years from Earth.

The black hole is in a galaxy called M87, and its diameter is estimated to be some 40 billion kilometers. The image, assembled from data gathered by eight radio telescopes around the world, shows light and gas swirling around the lip of a supermassive black hole, whose existence was theorized by Einstein more than a century ago but confirmed only indirectly.

Supermassive black holes are situated at the center of most galaxies, including ours, and are so dense that nothing, not even light, can escape their gravitational pull. Light gets bent and twisted around by gravity as it gets sucked into the abyss along with superheated gas and dust.

Honma Mareki, a professor of the National Astronomical Observatory of Japan, said that the new image confirmed Einstein's general theory of relativity. He is one of 200 scientists who contributed to the research.
