First dormant black hole discovered, First Sun-like star in black hole binary system discovered: First detected via positional shifts of visible companion [19] [20] [21] 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
Death by Black Hole: And Other Cosmic Quandaries is a 2007 popular science book written by Neil deGrasse Tyson. It is an anthology of several of Tyson's most popular articles, all published in Natural History magazine between 1995 and 2005, [ 1 ] and was featured in an episode of The Daily Show with Jon Stewart .
A black hole with the mass of a car would have a diameter of about 10 −24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than 200 times that of the Sun. Lower-mass black holes are expected to evaporate even faster; for example, a black hole of mass 1 TeV/c 2 would take less than 10 −88 ...
Subrahmanyan Chandrasekhar FRS (/ ˌ tʃ ə n d r ə ˈ ʃ eɪ k ər /; [3] 19 October 1910 – 21 August 1995) [4] was an Indian-American theoretical physicist who made significant contributions to the scientific knowledge about the structure of stars, stellar evolution and black holes.
Sagittarius A*, abbreviated as Sgr A* (/ ˈ s æ dʒ ˈ eɪ s t ɑːr / SADGE-AY-star [3]), is the supermassive black hole [4] [5] [6] at the Galactic Center of the Milky Way.Viewed from Earth, it is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic, [7] visually close to the Butterfly Cluster (M6) and Lambda Scorpii.
UCLA Faculty Research Lecture: Unveiling a Black Hole at the Center of the Milky Way; Finkbeiner, Ann (March 20, 2013), "As an early adopter of astronomical technology, Andrea Ghez is revealing secrets about the giant black hole at the Galaxy's centre", Nature, 495 (7441): 296–298, Bibcode:2013Natur.495..296F, doi: 10.1038/495296a, PMID 23518544
[4] [1] [5] This black hole is located 5,000 light-years away, has a mass 7.1 times that of the Sun, and moves at about 45 km/s. [6] While there have been other candidates, they have been detected more indirectly.
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.
