This is a list of known black holes that are close to the Solar System. It is thought that most black holes are solitary, but black holes in binary or larger systems are much easier to detect. [1] Solitary black holes can generally only be detected by measuring their gravitational distortion of the light from more
Black hole news: Mysterious flashing seen near supermassive black hole. Astronomers have an idea what it is ... launched in 1999 to detect X-ray emissions ... This article originally appeared on ...
Some examples of these models can be described within general relativity (quark and strange stars, [46] boson and Proca stars, [47] Kerr black holes with scalar and Proca hair [48]), others arise from some approaches to quantum gravity (cosmic strings, [49] fuzzballs, [50] gravastars [51]), or come from alternative theories of gravity ...
Known gravitational wave events come from the merger of two black holes (BH), two neutron stars (NS), or a black hole and a neutron star (BHNS). [ 9 ] [ 10 ] Some objects are in the mass gap between the largest predicted neutron star masses ( Tolman–Oppenheimer–Volkoff limit ) and the smallest known black holes.
The newly identified black hole is located about 2,000 light-years from Earth - relatively close in cosmic terms - in the constellation Aquila, and has a companion star orbiting it, researchers ...

A fourth detection of a black hole merger, between objects of 30.5 and 25.3 solar masses, was observed on 14 August 2017 and was announced on 27 September 2017. [ 54 ] In 2017, Weiss, Barish, and Thorne received the Nobel Prize in Physics "for decisive contributions to the LIGO detector and the observation of gravitational waves."
Black holes aren't evil.But they are fantastically weird, gravitationally powerful places. And astronomers suspect there are some 100 million of these objects — realms so dense that not even ...
