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

Physicists at Goethe University in Frankfurt, Germany, have used supercomputer simulations to predict a specific gravitational-wave fingerprint that would confirm quark-gluon plasma forms inside the ...

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

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

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

Astronomers have tracked a powerful blast of radiation back to its source, finding a neutron star collision within colliding galaxies.

Scientists believe this long stream of gas may have formed when several galaxies collided millions of years ago.

In 2023, astronomers using NASA’s Chandra X-ray Observatory and Hubble Space Telescope spotted an unusual class of short gamma-ray bursts, whose origin appeared to be the collision of two neutron ...

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 ...

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

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 ...

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 ...
