One of the most familiar stars in the night sky is also one of the most volatile, and astronomers say it is living on ...

One of the brightest stars in the night sky is a dying giant so bloated that, if it swapped places with the Sun, its surface ...

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 ...

Betelgeuse has always been something of a mystery. Betelgeuse is one of the brightest stars in the sky, marking the right ...

Primordial black holes may occasionally pass through white dwarf stars and trigger enormous Type Ia supernova explosions. Researchers found that these events could explain chemical patterns seen in ...

A rare stellar explosion has allowed astronomers to follow the death of a massive star from start to finish, yielding one of the most complete datasets ever collected for such an event. The explosion ...

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 ...

It was what's known as a "shock breakout": the first moment that a massive dying star reveals itself, as its collapsing core shoots a blast of X-rays and ultraviolet light from trapped energy breaking ...

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 ...

Artist’s impression of a hot core—a warm cocoon of molecular gas surrounding a newborn star—discovered in a supernova remnant. Blue represents high-energy regions produced by the supernova explosion, ...
