Neutron stars explained through stellar remnants and collapsed stars, revealing extreme density, gravity, magnetism, and ...

The collision of two neutron stars around 130 million light-years from Earth, and the unique physics this merger created, may have shed new light on dark matter. Axions have never been directly ...

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.

Scientists from several institutions, including the University of Chicago, discovered a lemon-shaped planet with an ...

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 ...

A new study showing how the explosion of a stripped massive star in a supernova can lead to the formation of a heavy neutron star or a light black hole resolves one of the most challenging puzzles to ...

Describing matter under extreme conditions, such as those found inside neutron stars, remains an unsolved problem. The ...

The oscillating frequencies of two short gamma-ray bursts are the best evidence yet for the formation of 'impossible' hypermassive neutron stars that can briefly defy gravity before collapsing to form ...

A double blast of dying stars may be the first observed case of a long-hypothesized, never proven “superkilonova.” Although ...

Sep. 12—In the cosmic tug-of-war between matter and antimatter, matter has the upper hand. Our universe leans more heavily on the side of matter. In a one-to-one ratio, matter and antimatter would ...
