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.
