Astronomers detect black holes swallowing up neutron stars for the first time

Astronomers detect black holes swallowing up neutron stars for the first time CNET 2 hrs ago © Carl Knox, OzGrav/Swinburne Astronomers have detected two neutron star-black hole mergers via gravitational waves the first time such a discovery has been made. On Jan. 5, 2020, astrophysicists heard a chirp from a distant part of the cosmos, some 900 million light-years away. The fleeting sound was unlike any they d heard before and was caused by a great ripple in space-time a gravitational wave that spread out across the universe from over 900 million light-years away, washing over the Earth and pinging detectors. Chirp.  Then, 10 days later, they heard another, similar sound. A cosmic twin. Gravitational waves had once again pinged Earth s detectors. 

Scientists detect gravitational waves from black holes devouring neutron stars

Last Updated: Scientists Detect Gravitational Waves From Black Holes Devouring Neutron Stars Scientists have discovered gravitational waves created by black hole and neutron star mergers for the first time after they discovered wave incident in January. Picture Credit: ANI Scientists have discovered gravitational waves created by black hole and neutron star mergers for the first time. In January 2020, a team of researchers discovered two gravitational wave incidents in a 10-day period from distances of more than 900 million light-years. The results of the research were reported in the Astrophysical Journal Letters journal. The Center for Computational Relativity and Gravitation (CCRG) at Rochester Institute of Technology-assisted in identifying crucial aspects of the merger occurrences.

Black hole and neutron star collide twice within 10 days

Vivien Raymond, from Cardiff University in the UK, said that the shock results were fantastic . We have to go back to the drawing board and rewrite our theories, Professor Raymond said. We have learned a bit of a lesson again. When we assume something we tend to be proved wrong after a while. So we have to keep our minds open and see what the universe is telling us. Black holes are astronomical objects that have such strong gravity, not even light can escape. Neutron stars are dead stars that are incredibly dense. A teaspoonful of material from a neutron star is estimated to weigh around four billion tonnes.
