Resumen de Star smash-up spotted
First came the gravitational waves. Then, a burst of gamma radiation. As night fell in Chile, a small telescope pinpointed the signals in the sky: the first ever neutron star collision found with gravitational waves. The discovery by the Laser Interferometer Gravitational-Wave Observatory (LIGO) on 17 August delivered many other firsts: the first gravitational waves detected from anything other than a pair of black holes, the first proof that neutron star mergers cause gamma ray bursts, the first sighting of heavy elements being formed and the first measurement of the universe's expansion using gravitational waves.
