Neutron Stars Collide in New LIGO Signal?

Season 3 Episode 39 | 11m 27s

Last year LIGO announced the detection of gravitational waves from the merger of two black holes. The science world went a little crazy. Only a few weeks ago a new rumour emerged: that LIGO had, for the first time, spotted gravitational waves from the collision of a pair of neutron stars. If it’s true, some long-standing astrophysical mysteries are about to be unlocked.
