![]() ![]() To complement the EHT findings, several NASA spacecraft were part of a large effort, coordinated by the EHT's Multiwavelength Working Group, to observe the black hole using different wavelengths of light. By getting radio telescopes around the world to work in concert like one instrument, the EHT team achieved this, decades ahead of time." "Years ago, we thought we would have to build a very large space telescope to image a black hole. "This is an amazing accomplishment by the EHT team," said Paul Hertz, director of the astrophysics division at NASA Headquarters in Washington. Catching its shadow involved eight ground-based radio telescopes around the globe, operating together as if they were one telescope the size of our entire planet. This black hole is 6.5 billion times the mass of the Sun. The stunning new image shows the shadow of the supermassive black hole in the center of Messier 87 (M87), an elliptical galaxy some 55 million light-years from Earth. Against a bright backdrop, such as this disk, a black hole appears to cast a shadow. By its very nature, a black hole cannot be seen, but the hot disk of material that encircles it shines bright. ![]() Anything that comes within a black hole's "event horizon," its point of no return, will be consumed, never to re-emerge, because of the black hole's unimaginably strong gravity. includes the National Science Foundation.Ī black hole is an extremely dense object from which no light can escape. EHT is an international collaboration whose support in the U.S. A black hole and its shadow have been captured in an image for the first time, a historic feat by an international network of radio telescopes called the Event Horizon Telescope (EHT). ![]()
