Gr@v warmly congratulates the Event Horizon Telescope collaboration for the first direct image of a black hole. This discovery has had a worldwide impact, including news coverage in Portugal with the contribution of Gr@v and former Gr@v members.
The image released targeted the supermassive black hole at the heart of the gigant elliptic galaxy M87. A lensed light ring (brigher in the south) is clearly seen, together with a dark inner region: the black hole shadow. The image is the result of Terabytes of data collected at the eight stations of the EHT network collected in April 2017.
