A type Ia supernova (SNIa) is commonly believed to be the thermonuclear explosion of a white dwarf star. These objects are the remnants of a normal star like our Sun in whose interior the fuel for ...

The James Webb Space Telescope has spotted a stellar explosion from a time when the cosmos was still in its infancy, catching the light of a supernova that detonated less than a billion years after ...

Shortly after the explosion, SN1993J was classified as a typical type-II supernova because hydrogen lines could be seen in its spectra. However, the hydrogen lines disappeared after a few weeks, ...

The cosmic record breaker has now been confirmed by astronomers, who see that the James Webb Space Telescope has detected what could possibly be the earliest supernova, the light of which was observed ...

The probable signature of an ageing massive star's stellar wind has been detected shortly after the star underwent a supernova explosion. The finding suggests that such windy stars can have bright, ...

A giant star that exploded 30 million years ago in a galaxy near Earth had a radius prior to going supernova that was 200 times larger than our sun, say astrophysicists. The massive explosion, ...
