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

A research team is using astrophysical explosions to understand the mysterious forces at work in some of the smallest building blocks in nature: atomic nuclei. In new research published in Nature ...

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 ...

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

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

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.

GW200105 reveals an eccentric orbit before merger, challenging formation models.

Researchers said this event, called GRB 230906A, is likely in a stream of gas located about 4.7 billion light-years from Earth.

Physicists have discovered a surprising new “Island of Inversion” in a place no one expected: among nuclei where the number ...

Most gamma-ray bursts—the brightest, most powerful explosions in the universe—are tracked back to the deaths of massive stars. But a new discovery suggests that such enormous explosions can come from ...
