The world's first-ever detection of two faraway neutron stars colliding, causing a massive blast that rippled through the fabric of space and time, is judged the scientific breakthrough of 2017.

The blast may have been a kilonova — a type of neutron star merger — in the wake of a more traditional supernova.

A science breakdown explores what would happen as you approach a neutron star, explaining the extreme gravity, radiation, and ...

A team of astronomers believe they've witnessed, for the first time, a star exploding in a mythical "superkilonova." ...
