Why astrophysicists are over the moon about observing merging neutron stars

When LIGO, the Laser Interferometer Gravitational-Wave Observatory, first detected gravitational waves from merging black holes, it opened up a new window in astrophysics and provided the most powerful confirmation yet of Einstein’s theory of general relativity. Now LIGO has done it again, together with the Virgo interferometer, this time by observing merging neutron stars – something astrophysicists had known must happen but had never been able to detect definitively until now. read more
