The Event Horizon Telescope (EHT) is a telescope array consisting of a global network of radio telescopes.The EHT project combines data from several very-long-baseline interferometry (VLBI) stations around Earth, which form a combined array with an angular resolution sufficient to observe objects the size of a supermassive black hole's event horizon.
Katherine Louise Bouman (/ ˈ b aʊ m ə n /; [1] born 1989) is an American engineer and computer scientist working in the field of computational imaging.She led the development of an algorithm for imaging black holes, known as Continuous High-resolution Image Reconstruction using Patch priors (CHIRP), and was a member of the Event Horizon Telescope team that captured the first image of a ...
On April 10, 2019, the Event Horizon Telescope collaboration released the first horizon-scale image of a black hole, in the center of the galaxy Messier 87. [2] In March 2020, astronomers suggested that additional subrings should form the photon ring, proposing a way of better detecting these signatures in the first black hole image. [38] [39]
In April 2019, the Event Horizon Telescope collaboration released measurements of the black hole's mass as (6.5 ± 0.2 stat ± 0.7 sys) × 10 9 M ☉. [74] This is one of the highest known masses for such an object. A rotating disk of ionized gas surrounds the black hole, and is roughly perpendicular to the relativistic jet.
Falcke predicted that near the edges of a black hole, there would be a 'black hole shadow' that could be detected by a radio telescope. [2] [9] This shadow was eventually observed with the Event Horizon Telescope. On 10 April 2019, the project announced that they created an image of the black hole at the centre of M87 . [13]
From alien life to human spaceflight, 2020 may deliver some exciting news.
[24] [25] [26] In 2019, Hecht was one of the scientists awarded the 2020 Breakthrough Prize in Fundamental Physics for his work with the Event Horizon Telescope to produce the first image of a supermassive black hole. [27] [28]
