A mysterious cosmic explosion has astronomers buzzing, as a strange event may hint at an entirely new kind of stellar ...

Astronomers have discovered that the birth of neutron stars with magnetic fields trillions of times stronger than Earth's ...

For the very first time, astronomers have captured a radio signal emitted by a very specific type of stellar explosion. This unprecedented observation offers us a glimpse into the final moments of a ...

An international team of astronomers reports the discovery of a new supernova remnant (SNR) using radio observations. The ...

This artist's animation shows a hypothe sized event known as a superkilonova . Initially, a massive star explodes in a supernova, which generates elements like carbon and iron. In the aftermath, two ...

Astronomers call this "eruptive mass loss," and it's a stellar drama we're still trying to fully grasp.

Earlier this year, a powerful gamma-ray burst traveled through space from a very distant source in the cosmos. The explosion was traced back to the early universe, just millions of years after the Big ...

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 ...

The James Webb Space Telescope is weighing in on a longstanding debate over why we don’t see more of the most massive red supergiant stars go supernova. NASA/ESA/CSA/Northrop Grumman In recent years, ...

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 ...
