Astronomers have taken the ever image of a black hole. It is in a distant called M87, 500 million trillion km from Earth. That is a five followed by twenty . Scientists say the black hole has a of 40 billion km and is three million times than Earth. The lead astronomer said: "What we see is larger than the of our entire Solar System. It has a 6.5 billion times that of the Sun....It is an absolute - the heavyweight champion of black holes in the Universe." He added that it was one of the heaviest black holes in .

The was captured by a network of eight telescopes called the Event Horizon Telescope (EHT). No telescope is powerful to record the image. The EHT telescopes are located on in Hawaii and Mexico, mountains in the USA and Spain, a in Chile, and in Antarctica. A of 200 scientists used the telescopes to scan the M87 galaxy over 10 . The was stored on hundreds of hard drives and processed to produce the image. It is now a in space exploration. A professor called it "an extraordinary feat".
