The first image (silhouette or shadow) of a black hole, taken of the supermassive black hole in M87 with the Event Horizon Telescope, released in April 2019. The black hole information paradox [1] is a paradox that appears when the predictions of quantum mechanics and general relativity are combined.
Yes, it happened. After years of relying on computer-generated imagery, scientists using the Event Horizon Telescope have captured the first real image of a black hole. The snapshot of the ...
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 ...
These black holes would then have more time than any of the above models to accrete, allowing them sufficient time to reach supermassive sizes. Formation of black holes from the deaths of the first stars has been extensively studied and corroborated by observations. The other models for black hole formation listed above are theoretical.

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 ...
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.
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 ...
