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

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

The final dance of a black hole and a neutron star before their ultimate merger has been revealed, according to new research.

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 ...

The catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples could upend a major theory about how these extreme pairs form.

Breakthrough discovery provides new clues about how these celestial bodies - that push the known laws of physics to their limits - find each other.

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 ...

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 ...

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 ...
