Soft X-rays kept flowing for about 560 seconds, or 9.3 minutes, after a gamma-ray burst that itself lasted well under a ...

Astronomers have found strong evidence that some mysterious, minutes-long X-ray flashes are produced when two neutron stars ...

Gamma rays from the explosion lasted roughly a third of a second. The X-rays kept going for what the research team calls ...

On July 4, 2025, astronomers watched a cosmic explosion do something it was not supposed to do. The event began with a ...

Astronomers say they have traced a puzzling type of bright X-ray flash to the collision of two neutron stars. The Einstein ...

Researchers using Murriyang, CSIRO's Parkes radio telescope, have detected unusual radio pulses from a previously dormant star with a powerful magnetic field. The paper, "Linear to circular conversion ...

Magnetars are a rare type of neutron star with an extremely strong magnetic field, and astronomers have been stumped on how these objects form. New observations of a magnetar 16,000 light-years from ...

Typically, magnetars rotate once every few seconds. And their rotation slows down only very slowly. Slowing down by a single rotation per second can take tens of thousands of years for a magnetar. Yet ...

In a new Caltech-led study, researchers from campus and the Jet Propulsion Laboratory (JPL) have analyzed pulses of radio waves coming from a magnetar—a rotating, dense, dead star with a strong ...
