On 2019 April 25, Laser Interferometric Gravitational Wave Observatory (LIGO) at Livingston reported a compact binary coalescence with a total mass ~ 3.4 solar mass. Though this is consistent with a binary neutron star merger, the total mass is significantly larger than all the known binary neutron stars. The gravitational wave observations cannot exclude the possibility of one or both of the binary constituents being black holes. In this talk, I will discuss the detection its astrophysical implications.
