group of stars that orbit a region in space. Alternatively, when gas falls into a stellar black hole from a companion star or nebula, the gas spirals inward, heating to very high temperatures and emitting large amounts of radiation that can be detected from earthbound and Earth-orbiting ...
matter flowing into it from its companion becomes intensely heated and then radiatesX-rayscopiously before entering the event horizon of the black hole and disappearing forever. One of the component stars of the binary X-ray systemCygnus X-1is a black hole. Discovered in 1971 in theconstellation...
The first black hole ever discovered was Cygnus X-1, located within the Milky Way in the constellation of Cygnus, the Swan. Astronomers saw the first signs of a black hole in 1964 when a sounding rocket detected celestial sources of X-raysaccording to NASA. In 1971, astronomers determined t...
Solving the KG equation or Dirac equation near the event horizon of the black hole, one can obtain a set of positive frequency modes propagating in the exterior and interior regions of the event horizon. Here, we introduce the quantization of Dirac fields, in this case the positive (fermions...
[01:22.04]The newly discovered gravitational mass was identified [01:26.96]by observing the motion of its orbiting star. [01:31.24]The star orbits the black hole [01:34.32]at about the same distance as Earth orbits the su...
Astronomers have discovered the closest black hole to Earth, the first unambiguous detection of a dormant stellar-mass black hole in theMilky Way. Its close proximity to Earth, a mere 1,600 light-years away, offers an intriguing target of study to advance understanding of the evolution of bina...
NASA reported in June 2015 that scientists discovered a series of "eruptions" in a supermassive black hole found in the NGC 5813 group of galaxies, using the Chandra X-ray Observatory. Multiple eruptions over 50 million years rearranged the cosmic landscape at the center of the galaxies, NASA ...

The study aims to determine the distance of the star containing black holes that changes position during Earth's motion. The researchers found that the star is just 2,390 parsecs from the planet and the tool can help in determining the holes behavior....
