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 may be one step closer to unlocking one of the great mysteries of the universe after calculating that neutron stars might hold a key to helping us understand elusive dark matter. Scientists ...

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 ...

Describing matter under extreme conditions, such as those found inside neutron stars, remains an unsolved problem. The density of such matter is equivalent to compressing around 100,000 Eiffel Towers ...
