One of the brightest stars in the night sky is living on borrowed time, at least by cosmic reckoning. Betelgeuse, the ruddy ...

Betelgeuse is a nearby red supergiant living through the late stages of a massive star’s life. It will eventually end in a supernova, and models of such an event suggest a display bright enough to ...

When a star reaches its final stages of life, it ends in a bright, powerful explosion called a supernova and scatters ...

Astronomers watch star explode like never before – and find an entirely new way for them to die - Observations from across ...

Astronomers have linked an X-ray flash discovered by the Einstein Probe to a known type of supernova with unusual features ...

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 ...

A collapsing star drives a shock wave out through its own body. The wave reaches the surface and breaks through, dumping ...

Astronomers are puzzling over an oddball gamma ray burst that may have accompanied a supernova that is still in the process of brightening. NASA’s Swift satellite detected a burst of high-energy gamma ...

These images show the evolution of supernova SN 2026gzf, which was first detected by the Einstein Probe on 21 March 2026. Images taken on 25 March and 3 April 2026 show the supern ...
