Gravitational Wave scientists of LIGO and VIRGO collabration, including CGA astrophysicists announced detection of gravitational wave that is the result of collision of a black hole around 23 times the size of the Sun with a much smaller object 2.6 solar mass. This mystrious object falls within the astrophysical mass gap between ordinary black holes and neutron stars, making it either the heaviest neutron star or the lightest black hole ever discovered. 

This gravitational wave source, that came from a distance of around 800 million light years, was detected on 14 August 2019. This is the first detection of gravitational waves from collision of two astrophysical objects with unequal masses.
