A neutron star collision detected by gravitational waves is Science's 2017 Breakthrough of the Year.
Gravitational waves are ripples in time-space that only occur under a handful of extreme cosmic conditions.



NASA’s Swift satellite has captured an event in the cosmos like nothing ever seen before, researchers say in the 17 June issue of Science.
