A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an ...

Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and particles, including a ...

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known ...

The catalog of gravitational waves "heard" by LIGO, KAGRA and Virgo has doubled with detections of spacetime ripples.

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, ...

The transformation of neutrinos in a neutron star merger could be crucial to shaping the way events of the collision unfold. For the first time, a team of physicists has simulated how neutrinos change ...

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of ...

Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of subatomic particles with no electric charge (i.e., neutrons). When two ...
