1972 — Jacob Bekenstein suggests that black holes have an entropy proportional to their surface area due to information loss effects; 1974 — Stephen Hawking applies quantum field theory to black hole spacetimes and shows that black holes will radiate particles with a black-body spectrum which can cause black hole evaporation
OGLE-2011-BLG-0462 was discovered through microlensing when it passed in front of a background star that was 20,000 light years away from Earth. The black hole's gravity bent the star's light, causing a sharp spike in brightness that was detected by the Hubble Space Telescope. It took six years to confirm the existence of OGLE-2011-BLG-0462.
Now, an international team of astronomers analyzing over 500 images across 20 years from NASA’s Hubble Space Telescope report that they’ve identified a black hole some 17,700 light-years away ...
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.
New find challenges our understanding of where such objects come from
First dormant black hole discovered, First Sun-like star in black hole binary system discovered: First detected via positional shifts of visible companion [21] [22] [23] 1986—2022 3,000 ly (2.8 × 10 16 km; 1.8 × 10 16 mi) V616 Monocerotis (A0620−00) 5.86 M ☉ (1.165 × 10 31 kg; 2.57 × 10 31 lb) Visible variable star X-ray binary system
NASA researchers combined years of data and new imaging techniques to learn more about a "tipped over" black hole that is moving in an unexpected way. The black hole is located in a galaxy called ...
The object itself was detected in ESO images dating back to 1980, but its identification as a quasar occurred only several decades later. [2]An automated analysis of 2022 data from the European Space Agency's Gaia satellite did not confirm J0529-4351 as too bright to be a quasar, and suggested it was a 16th magnitude star with a 99.98% probability.
