The Secret Lives Of Neutron Stars
On August 17, 2017, astrophysicists witnessed two dead stars’ remnant cores, known as neutron stars, colliding into each other in a distant galaxy. Known as a neutron star merger, they detected this event via ripples in spacetime—known as gravitational waves—and light produced by the resulting explosion. This marked the first and only time scientists had seen such an event using gravitational waves. From those signals, they deduced that the neutron stars were 1....
