Using NASA’s Chandra X-ray Observatory and other telescopes, astronomers have traced a short-duration gamma-ray burst event called GRB 230906A to a faint dwarf galaxy embedded in a vast stream of ...

Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an ...

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 ...

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 ...

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...

Rochester Institute of Technology is advancing computer simulations to predict, for the first time, the complete cycle of neutron stars merging with other neutron stars or black holes. These extreme ...

Some of the universe’s densest objects can twist, stretch, and resonate in ways that challenge even the most seasoned physicists. Neutron stars, the remnants of massive stars that have exploded as ...

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