Physicists have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions could form an explanation for the elusive dark matter that ...

A neutron star and black hole were detected merging along an unusual oval orbit, challenging long-held theories about how these systems form.

The findings confirm a theory first proposed 16 years ago by University of California, Berkeley theoretical astrophysicist ...

The discovery of a newborn magnetar inside a distant supernova helps explain why some stellar explosions shine far brighter ...

The catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples ...

Researchers said this event, called GRB 230906A, is likely in a stream of gas located about 4.7 billion light-years from Earth.

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 ...

Astronomers have discovered that the birth of neutron stars with magnetic fields trillions of times stronger than Earth's magnetosphere is the "magic trick" behind superbright supernovas.

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 ...

Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...
