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

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

One of the brightest stars in the night sky is living on borrowed time, and its eventual death promises to be one of the great spectacles of the cosmos. When the aging red supergiant that marks the ...

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

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 ...

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

Astronomers capture a rare shock breakout as a massive Wolf-Rayet star explodes into a broad-lined Type Ic supernova, revealing new clues about stellar deaths, black hole formation, and why some blast ...

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

The Karoo-based Southern African Large Telescope (SALT) has played a significant role in an urgent international collaboration to monitor a rarely observed phenomenon: the actual start and development ...

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 ...

The supernova world has a new brightness champ. A supernova discovered on 14 June appears to shine more than 400 billion times brighter than the sun would if they sat next to each other. An ordinary ...

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 ...
