Astronomers using the NASA/ESA Hubble Space Telescope have observed a visible counterpart to gravitational waves for the first time: a kilonova from merging neutron stars.
For the first time, Hubble has observed the source of a gravitational wave: the merging of two neutron stars. This merger created a kilonova — an object first predicted by theory more than 30 ago. This event also provides the strongest evidence yet that short duration gamma-ray bursts are caused by mergers of neutron stars. These observations may help solve another long-standing question in astronomy: the origin of heavy chemical elements, like gold and platinum. In the merger of two neutron stars, the conditions appear just right for their production.
