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 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 ...

When massive stars collapse, they can form neutron stars—objects so dense that atoms themselves are crushed apart. But some ...

Neutron star mergers are collisions between neutron stars, the collapsed cores of what were once massive supergiant stars. These mergers are known to generate gravitational waves, energy-carrying ...

Strange matter only occurs under very specific circumstances -- and astrophysicists are getting closer to understanding what ...

Researchers have developed a new artificial intelligence powered simulation that could significantly improve our understanding of how the universe ...

When a black hole and a neutron star finally meet, the result is cosmic carnage—and now, thanks to Caltech’s latest supercomputer simulations, we’re getting a front-row seat to the whole terrifying ...

Artist’s impression of the powerful winds blowing from the bright X-ray source GX13+1. The X-rays are coming from a disc of hot matter, known as an accretion disc, that is gradually spiralling down to ...

Neutron stars are among the most exotic and extreme objects in the universe. These fascinating remnants form from massive stars that have reached the end of their life cycles. When such stars exhaust ...
