Mystery astronomical object may be a ‘black neutron star’

The video explores the life cycle of stars, focusing on their transformation into neutron stars or black holes. It highlights a recent discovery by LIGO and Virgo of a mysterious object in the mass gap between neutron stars and black holes. This object, possibly the lightest black hole or the heaviest neutron star, was part of a binary system with a larger black hole. Their collision emitted gravitational waves detected in 2019, leading to new insights into stellar evolution.
