Hubble Space Telescope finds star collision’s jet travels fast

In August 2017, astronomers witnessed an incredible explosion in space — two ultra-dense neutron stars collided head-on, releasing an extraordinarily powerful jet of radiation.

Two days later, the Hubble Space Telescope was on the scene studying that jet. Now, five years after the event, which was astronomers’ first detection of gravitational waves from neutron stars, researchers have finally been able to measure the speed of the jet.
