In a strange turn of events, a supernova birthed twin baby neutron stars that merged to make a powerful kilonova. Reading time 3 minutes When massive stars die, they go out in fiery explosions called ...

When a black hole and a neutron star finally meet, the result is cosmic carnage—and now, thanks to Caltech’s latest supercomputer simulations, we’re getting a front-row seat to the whole terrifying ...

Merging neutron stars are excellent targets for multi-messenger astronomy. This modern and still very young method of astrophysics coordinates observations of the various signals from one and the same ...

In a major breakthrough, scientists have simulated in unprecedented detail how a neutron star cracks just seconds before being swallowed by a black hole. The simulation, led by Caltech astrophysicist ...
