A relativistic jet after the kilonova

An article published in the journal “Nature” describes the observations of a relativistic jet that followed the merger between two neutron stars discovered in August 2017, the first case of an event detected and studied in both electromagnetic and gravitational waves. A team of researchers used the precise measurements made with some radio telescopes to establish that a narrow jet of particles was emitted at a speed close to that of light after the event.
