Oct 2017 Neutron Stars in Collision – Astronomically Significant!

 by Pat Browne

The October 2017 announcement of the detection of a gravitational wave event, GW170817 from the merger of two neutron stars are producing  significant  discoveries across ‘the full spectrum’ of astronomical research.

This event produced not only LIGO-VIRGO gravitational wave signals but also  electromagnetic (spectral) results  and  the gamma ray burst GRB 170817A    – all from this single event. The event marks a series of significant FIRSTS from collaborating astronomical observatories.

Here’s a video describing in detail the significant astronomical discoveries: Ripples in Space, Flashes in Light – Caltech
