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.
After two years of data processing, EHT released its first image of a black hole, at the ceneter of the Messier 87 galaxy. [155] [156] 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 ...
Size comparison of the event horizons of the black holes of TON 618 and Phoenix A.The orbit of Neptune (white oval) is included for comparison. As a quasar, TON 618 is believed to be the active galactic nucleus at the center of a galaxy, the engine of which is a supermassive black hole feeding on intensely hot gas and matter in an accretion disc.
This is the first image of Sagittarius A* (or Sgr A* for short), the supermassive black hole at the center of the Milky Way galaxy, 27,000 light-years from Earth. It's the first direct visual ...

Over a year ago, a group of researchers made a revolutionary breakthrough when they successfully captured the first-ever image of a celestial phenomenon — a black hole. The short sequence of ...
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]
Hubble Space Telescope image of galaxy NGC 5084's core. A dark, vertical line near the center shows the curve of a dusty disk orbiting the core, suggesting a supermassive black hole inside.
