A Mississippi State physicist has produced a direct laboratory measurement of a key nuclear reaction believed to occur during ...

Astronomers have discovered that rapidly spinning extreme dead stars or pulsars push it to the edge, blasting out radio ...

The study shows how some stars churn out heavy elements with no roadblock.

As binary neutron stars spiral around each other to merge, their gravitational tidal forces distort each other's shape and structure, potentially revealing clues as to what lies within them.

A newly analyzed gravitational-wave event has revealed something unexpected about one of the Universe’s most violent ...

Neutron stars escape collapse into a black hole thanks to degeneracy pressure produced by their neutrons, which is able to fight the crushing force of gravity. What exactly lies at the heart of a ...

"For the most part, massive stars make black holes. The more massive the star, the heavier the black hole," Fishbach said, until stars reach a certain mass threshold beyond which the physics of their ...

Scientists have precisely measured two unstable atomic nuclei that play a crucial role in explosive X-ray bursts on neutron stars. The results reveal faster nuclear reactions than previously thought, ...

Neutron stars—the dense remnants of massive stellar explosions—and their presence in X‐ray binaries serve as natural laboratories for extreme physics. In these systems, matter is transferred from a ...

Astronomers have spotted a jaw-dropping collision between two neutron stars – and it may have produced gold and platinum. The discovery in a tiny, faraway galaxy is the first time this has been seen ...
