The black hole’s boundary — the event horizon from which the EHT takes its name — is around 2.5 times smaller than the shadow it casts and measures just under 40 billion km across. While this may sound large, this ring is only about 40 microarcseconds across — equivalent to measuring the length of a credit card on the surface of the Moon.
To create the footage, the Event Horizon Telescope team — the research group behind the discovery of the original black hole image — dug out old data and combined it with a mathematical model ...

The black hole was imaged using data collected in 2017 by the Event Horizon Telescope (EHT), with a final, processed image released on 10 April 2019. [13] In March 2021, the EHT Collaboration presented, for the first time, a polarized-based image of the black hole which may help better reveal the forces giving rise to quasars. [14]
The first image of a black hole just became even more fascinating. At the center of the Messier 87 (M87) galaxy is a supermassive black hole about 38 billion kilometers wide, a behemoth so dense ...
Three years after capturing the first image of a supermassive black hole in a galaxy 55 million light years away, astronomers have managed to "photograph" one closer to home.
After two years of data processing, EHT released its first image of a black hole, at the center of the Messier 87 galaxy. [157] [158] What is visible is not the black hole—which shows as black because of the loss of all light within this dark region. Instead, it is the gases at the edge of the event horizon, displayed as orange or red, that ...
