On Aug. 17, 2017, gravitational waves from a neutron-star collision were detected for the first time ever by LIGO and Virgo collaborations and - in another first - light from the event has been captured by observatories in space and on Earth. The source has been designated GW170817 and is described as a "kilonova" event.

Hubble Space Telescope observes source of gravitational waves
The Hubble Space Telescope operated by NASA and the European Space Agency captured imagery of the source of the gravitational waves detection. Learn more about it from the Hubblecast video:
'Kilonova' from neutron star merger observed by multiple ESO telescopes
Several European Southern Observatory telescopes in Chile's Atacama Desert were used to discover the "kilonova," the merging of the neutron stars. Learn more about it in this ESOCast video:
