On October 16, physicists announced that the Advanced Laser Interferometer Gravitational-Wave Observatory, LIGO, and VIRGO, the European Gravitational Observatory, detected gravitational waves from a neutron star merger that emitted high-energy light shortly after merging.

The Fermi space telescope spotted that light coming from the same region of the sky 1.7 seconds after the gravitational wave detection that proved for the first time that gravitational waves, the ripples in spacetime set off when massive bodies collide, travel at the speed of light to within a tenth of a trillionth of a percent.
