August 17 2017 will go down in in Astrophysics history . A LIGO event triggered a 50 telescope 24 hour 360 degree operation which yielded astronomy gold.  Prof Tara Murphy was at ground zero when the results came in but she would have to be patient for the ripples to show up on Australian Radio Telescopes. In the data was the solution to a Cold war mystery. A compelling first hand account of a new frontier of discovery.
