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.

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

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 ...

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 ...

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 ...

The cosmos has delivered a rare kind of fireworks display, and astronomers are racing to understand what it means. A strange double flash from a distant galaxy appears to show two neutron stars ...
