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.

In this image of M87* taken on 11 April 2017 (a representative example of the images collected in a global 2017 EHT campaign), the shadow of a black hole is the closest we can come to an image of the black hole itself, a completely dark object from which light cannot escape.
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.
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 ...
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 ...
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]
These black holes could be the seeds of the supermassive black holes found in the centres of most galaxies. [129] It has further been suggested that massive black holes with typical masses of ~10 5 M ☉ could have formed from the direct collapse of gas clouds in the young universe. [125]
