Our simulations, which are based on the motion of magnetic fields and hot gas near the black hole, showed that the jets are powered by the black hole itself. In a news release about the breakthrough, Gammie said: "One of the great mysteries in astronomy has been how such jets are launched. When they compared the images, researchers found that all of them depicted a "ring" around the black hole that was roughly the same diameter, with a brighter segment in its southern arc. To ensure the final image's validity, the EHT project used a "blind" process, assigning four teams to spend seven weeks working independently to create an image based on data about the M87 black hole that was collected on April 11. Some of that work took place in Massachusetts, at MIT's Computer Science and Artificial Intelligence Lab, where computer scientist Katie Bouman "led the creation of a new algorithm to produce the first-ever image of a black hole," the lab said Wednesday.īouman, who was a graduate student when she began working on the project, gave a TEDx Talk in late 2016 in which she discussed the challenge of using algorithms to "piece together pictures from the sparse, noisy data" from telescopes - without, she added, biasing the system to gravitate toward what scientists might expect a black hole to look like.

Researchers at the Event Horizon Telescope project say they were able to create an image of a black hole by using a network of eight radio telescopes to create "a virtual telescope dish as large as the Earth itself," the National Science Foundation says. We have seen and taken a picture of a black hole," said EHT Director Shep Doeleman of Harvard University. "We are delighted to be able to report to you today that we have seen what we thought was unseeable. The enormous black hole is some 55 million light-years from Earth in the Virgo galaxy cluster, with a mass some 6.5 billion times that of our sun. "As an astrophysicist, this is a thrilling day for me," said National Science Foundation Director France A. The image shows a dark disc "outlined by emission from hot gas swirling around it under the influence of strong gravity near its event horizon," the consortium said. The world is seeing the first-ever image of a black hole Wednesday, as an international team of researchers from the Event Horizon Telescope project released their look at the supermassive black hole at the center of galaxy Messier 87 (M87). The first-ever image of a black hole was released Wednesday by a consortium of researchers, showing the "black hole at the center of galaxy M87, outlined by emission from hot gas swirling around it under the influence of strong gravity near its event horizon."Įvent Horizon Telescope collaboration et al ![]()
