Astronomers Have Discovered A Swarm Of Black Holes Using The Hubble Space Telescope! (SpaceFix) 4K
Researchers have proposed a new method for searching for black holes, which indicated the possibility of the existence of objects much smaller than any previously known.
Over the years, astronomers have studied black holes that form during supernova explosions and have tremendous gravity, as well as neutron stars – less dense objects that remain after the death of stars, not much larger than the Sun.
After decades of observing the universe, scientists have learned that black holes are about 5-15 times the mass of the Sun, and neutron stars are often 2.1 times. Because if a star dies 2.5 times heavier than the Sun, then it must collapse into a black hole. but a window in the range between the smallest known black holes and the largest neutron stars confused many researchers, so astrophysicists from Ohio State University decided to unravel this mystery..
The team began to study data from the analysis of 100 light spectra 000 stars of the Milky Way, collected during the Apache Point Observatory study of galactic evolution. Wavelength offset to the blue and red edge, allows you to determine that the star is orbiting an invisible object.
After narrowing the search to a potentially suitable 200 systems, astronomers have discovered a red giant orbiting something much smaller than the known black holes but larger than neutron stars. After additional calculations and verification with data from the Gaia satellite, they realized that they had found a black hole with a low mass, which is about 3.3 times heavier than the Sun.
Besides the fact that the researchers used a new search method, they potentially identified the first representative of a new class of black holes that they did not know about before..
Recall that astronomers will present the first real video of a black hole in 2020.
