|For the first time, a faint signal caused by the merging of two almost equally mysterious objects – a black hole and a neutron star – has been recorded on Earth.|
On January 5 2020, when the world was first learning of the COVID-19 outbreak, gravitational waves from this merging reached the Livingston detector of the Laser Interferometer Gravitational-wave Observatory (Ligo) gravitational wave observatory in Louisiana, US.
On January 15, the second gravitational wave event from a merger between a black hole and a neutron star, the densest stars in the universe, was discovered.
These two recordings are the first mergers between a black hole and a neutron star to have been detected on Earth. Black hole-neutron star binary systems, where a black hole and a neutron star orbit each other, had been predicted but never observed – until now.
