How we discovered gravitational waves from ‘neutron stars’ – and why it’s such a huge deal

Rumours have been swirling for weeks that scientists have detected gravitational waves – tiny ripples in space and time – from a source other than colliding black holes. Now we can finally confirm that we’ve observed such waves produced by the violent collision of two massive, ultra-dense stars more than 100m light years from the Earth.

The first direct detection of gravitational waves, a phenomenon predicted by Einstein’s 1915 general theory of relativity, was reported by scientists in 2016. Armed with this “discovery of the century”, physicists around the world have been planning new and better detectors of gravitational waves.
