The collision and merger of two neutron stars—the incredibly dense remnants of collapsed stars—are some of the most energetic events in the universe, producing a variety of signals that can be ...

Astronomers have witnessed the titanic collision between two neutron stars that resulted in the birth of the smallest black hole ever seen and forged precious metals like gold, silver, and uranium.

When the remnants of two stars collide, their union can launch a dazzling jet of high energy matter. A new computer simulation reveals how the merger, which forms a black hole, emits that bright beam, ...

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 ...

When two neutron stars collide, they unleash some of the most powerful forces in the universe, creating ripples in spacetime, showers of radiation, and even the building blocks of gold and platinum.

Gravitational-wave astronomy, one of the newest and most exciting fields in science, may soon take a major step forward ...

Neutrinos, ghostly particles barely interacting with matter, may secretly be reshaping the fates of massive stars. New research suggests that as stars collapse, they form natural "neutrino colliders," ...

On the outskirts of the Milky Way, one of the rarest kinds of stars in the galaxy has just become even more mysterious than it was before. Astronomers have used the Hubble and Gaia telescopes to study ...

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how ...
