Astronomers have taken the ever photograph of a black hole. It is located in a far, galaxy called M87, which is 500 million km from Earth. That number is a five followed by twenty zeroes. Scientists estimate the black hole to have a of 40 billion km and to be three million times larger than our planet. Lead Professor Heino Falcke spoke to the BBC about the black hole. He said: "What we see is larger than the of our entire Solar System. It has a 6.5 billion times that of the Sun. And it is one of the heaviest black holes that we think exists. It is an absolute - the heavyweight of black holes in the Universe."

The image of the black hole was captured by an of eight linked telescopes called the Event Horizon Telescope (EHT). No telescope exists that is enough to capture the image. Each of the EHT telescopes is located high up on in Hawaii and Mexico, mountains in the USA and Spain, a in Chile, and in Antarctica. A team of 200 scientists pointed the networked telescopes towards the M87 and scanned it over a period of 10 days. The they gathered was stored on hundreds of hard . It was then collated and processed to produce the image that is now a in space exploration. Professor Sheperd Doeleman called it "an extraordinary scientific ".
