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 ...
A Chandra X-Ray Observatory image of Cygnus X-1, which was the first strong black hole candidate discovered. X-ray binaries are binary star systems that emit a majority of their radiation in the X-ray part of the spectrum. These X-ray emissions are generally thought to result when one of the stars (compact object) accretes matter from another ...
The famous first picture of the supermassive black hole at the heart of our galaxy might not be accurate, a new study has claimed. The picture – initially published in 2022, after years of ...
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 ...
Cygnus X-1 (abbreviated Cyg X-1) [11] is a galactic X-ray source in the constellation Cygnus and was the first such source widely accepted to be a black hole. [12] [13] It was discovered in 1964 during a rocket flight and is one of the strongest X-ray sources detectable from Earth, producing a peak X-ray flux density of 2.3 × 10 −23 W/(m 2 ⋅Hz) (2.3 × 10 3 jansky).
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.

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.
