Neutron stars are the remnants of massive stars that have undergone supernova explosions, packing the mass of the Sun into a city-sized object. The observed binary system involved two neutron stars orbiting each other, emitting gravitational waves as they gradually approached their dramatic merger.
The detection not only adds a new composition to the cosmic symphony but also contributes to our understanding of the properties of neutron stars and the nature of extreme astrophysical events. Gravitational wave astronomy has opened a new realm of exploration, allowing scientists to study phenomena that were previously hidden from traditional telescopic observations.
