Illustration of a white dwarf siphoning material from its companion star. Over time, the white dwarf star can no longer support its own weight and implodes, creating a Type Ia supernova. NASA's Kepler ...

A NEARBY star is about to reach supernova, which may finally make it visible to the naked eye. This is a once-in-a-lifetime event, according to Nasa, as this reoccurring nova outburst only happens ...

Astronomers are eagerly anticipating the sight of an exploding star, T Corona Borealis, which will be visible to the naked eye for the first time in 80 years. The phenomenon, also known as T Cor Bor, ...

An international team of astronomers has discovered a teardrop-shaped star that it predicts is about to explode in a supernova. The star's unusual shape is caused by a nearby white dwarf distorting ...

A white dwarf star has been spotted 'switching on and off' in just 30 minutes. Astronomers say the event has previously only been seen to happen over a period of days and months. Using data from ...

A study of supernova remnant SNR 0519-69.0 using the Chandra X-ray telescope, Hubble and more has narrowed down its age to several hundred of years. The remnant is located in the "Large Magellanic ...

Astronomers have captured the clearest-ever close-up images of two exploding stars, events known as novae, within days of their eruption. These detailed images show that such explosions are far more ...

Learn how gravity and mass are pulling two stars into tighter, faster orbit around each other, with an explosive collision inevitable. In this picture, we capture the binary in the moment where the ...

Clumps of debris from a disrupted planetesimal are irregularly spaced on an long and eccentric orbit around the white dwarf -Credit:Dr Mark Garlick/The University of Warwick The 'white dwarf' star ...

An exploding supernova in a galaxy 70 million light-years away has been recorded by the Hubble Space Telescope. The rare event outshone the entire host galaxy, coming from a white dwarf star that ...
