The new Webb observations involve a supermassive black hole called LID-568 that existed when the cosmos was about 11% its current age - about 1.5 billion years after the Big Bang event 13.8 ...
The term "black hole" was used in print by Life and Science News magazines in 1963, [61] and by science journalist Ann Ewing in her article " 'Black Holes' in Space", dated 18 January 1964, which was a report on a meeting of the American Association for the Advancement of Science held in Cleveland, Ohio.

Scientists studying the earliest black holes may have found an answer to dark matter, putting Stephen Hawking’s theory on the subject back into the spotlight.
Given the universe is 13.7 billion years old, that puts the age of this black hole at 13.2 billion years. Even more astounding to scientists, this black hole is a whopper — 10 times bigger than ...
The supermassive black hole at the core of Messier 87, here shown by an image by the Event Horizon Telescope, is among the black holes in this list. This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses (M ☉), approximately 2 × 10 30 kilograms.
A quasar (/ ˈkweɪzɑːr / KWAY-zar) is an extremely luminous active galactic nucleus (AGN). It is sometimes known as a quasi-stellar object, abbreviated QSO. The emission from an AGN is powered by a supermassive black hole with a mass ranging from millions to tens of billions of solar masses, surrounded by a gaseous accretion disc.
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. Given its observed redshift of 2.219, the light travel time of TON 618 is estimated to be approximately 10.8 billion years.
In 1974, Hawking predicted that black holes might not be the bottomless pits we imagine them to be -- and now, there may be evidence to support that theory.
