In 1987, earthbound observers saw a star explode in the nearby dwarf galaxy called the Large Magellanic Cloud. Astronomers eagerly studied this supernova–the closest seen in the past 300 years–and ...

This artist's concept visualizes a kilonova – an explosion that happens when two neutron stars or a neutron star and a black hole collide and merge. When these collisions happen, a fraction of the ...

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 ...

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 team of physicists from the universities of Amsterdam, Princeton and Oxford have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions ...

Gold, uranium, and other heavy elements on Earth did not form here. They were born in the violent deaths of massive stars and the collisions of neutron stars, traveling across the galaxy before ...

WASHINGTON, Feb 12 (Reuters) - The formation of a black hole can be quite a violent event, with a massive dying star blowing up and some of its remnants collapsing to form an exceptionally dense ...
