Neutron star merger launched superfast ‘jet’ of materials

The neutron star merger, known as GW170817, occurred 130 million light-years from Earth and sent a burst of both gravitational and electromagnetic waves rippling through space that reached the Earth one year ago.
In the aftermath of the violent collision, GW170817 was observed worldwide by telescopes across the electromagnetic spectrum. By tracking changes in the optical, radio, and X-ray emission of the afterglow, scientists including Swinburne's Dr Adam Deller, from OzGrav, were able to study how the material flung out during the merger interacted with its surroundings.
