GRB 230906A, a short gamma-ray burst first detected in 2023, points to a faint galaxy embedded within a long stream of torn ...

Physicists at Goethe University in Frankfurt, Germany, have used supercomputer simulations to predict a specific ...

The four gravitational wave observatories around the world have been busy lately, revealing hundreds of detections. These ...

A neutron star and black hole were detected merging along an unusual oval orbit, challenging long-held theories about how these systems form.

Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of ...

The catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples ...

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 ...

NASA missions have discovered evidence of a rare neutron star collision in a tiny, distant galaxy, potentially shedding light ...

A newly analyzed gravitational-wave event has revealed something unexpected about one of the Universe’s most violent encounters. Scientists have found the first strong evidence that a black hole and 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 ...

More than 4,000 astronomers on Monday revealed the first-ever detection of two neutron stars colliding in space. Such objects are the skeletons of massive stars that have cataclysmically exploded, ...

Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an oval-shaped orbit just before merging. This unusual motion, detected in the ...
