The blast may have been a kilonova — a type of neutron star merger — in the wake of a more traditional supernova.

A novel astronomical event, termed a "superkilonova," is proposed to explain the coincident detection of gravitational waves (S250818k), indicating a subsolar-mass neutron star merger, and an ...

Axions are the most likely candidate for enigmatic dark matter that dominates the universe. Astrophysicists are searching for evidence of high-mass axions produced during supernovae. Scientists ...

Astronomers have discovered an extraordinary celestial system containing a runaway pulsar fleeing the scene of a massive stellar supernova explosion. What makes this system even more spectacular is ...
