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 ...

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

Neutron stars are formed when giant stars run out of fuel. Their internal pressure is no longer sufficient to fight gravity, and the resulting collapse and supernova explosion leaves a tiny core, with ...

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 ...

A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an ...

(THE CONVERSATION) Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and ...

Quantum computing and neutron star physics are converging on the same hard problem: how to describe matter when gravity and quantum mechanics both refuse to stay in the background. Researchers are ...

A distant neutron star has abruptly erupted in brightness, surging to roughly one hundred times its usual output and leaving astronomers scrambling to explain what could drive such a violent change.
