Four stars with unusual chemical ingredients may not need exceptionally powerful explosions to explain their origins. New ...

Scientists have precisely measured two unstable atomic nuclei that play a crucial role in explosive X-ray bursts on neutron stars. The results reveal faster nuclear reactions than previously thought, ...

For decades, astronomers have identified collisions between two neutron stars through bursts of gamma rays that can disappear in less than two seconds. But some of these violent encounters may also ...

A brief collision between two dead stars may leave a much longer signal than astronomers once expected. Researchers have ...

A neutron star collision produced an unusual nine-minute X-ray glow, possibly powered by a newborn magnetar that kept releasing energy after the blast.

There’s a star racing through our galaxy at more than 110,000 miles per hour, and it’s basically a cosmic horror show. Astronomers have been tracking SGR 0501+4516, a bizarre “zombie star” with a ...

Artist’s conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of general relativity. Some models of magnetars suggest that high-speed jets ...

Astronomers have discovered the first radio signals from a unique category of dying stars, called Type Ibn supernovae, and these signals offer new insights into how massive stars meet their demise.
