The results indicate that the elements essential for life formed within extreme, highly energetic environments deep inside stars, far removed from the calm conditions required for life itself. The ...

Imagine being able to view microscopic aspects of a classical nova, a massive stellar explosion on the surface of a white dwarf star, in a laboratory rather than from afar via a telescope. Cosmic ...

Australian astronomers have captured never-before-seen photos of an exploding giant star, 100 times bigger than the sun. The imagery of the supernova shows a powerful burst of light as a shock wave ...

Stars like the Sun are remarkably constant. They vary in brightness by only 0.1% over years and decades, thanks to the fusion of hydrogen into helium that powers them. This process will keep the Sun ...

"The sheer amount of radiated energy from these bursts is so large that you can't power them with a core collapse stellar ...

NASA is celebrating the holiday season with photographs of the remnants of a supernova star captured by the James Webb Space Telescope. The star, named Cassiopeia A (Cas A), shines brightly from ...

ASTRONOMERS will be able to see the brightest exploding star for 40 years – with just a pair of ­ordinary binoculars. The supernova, known as PTF11kly, is 21million light years away in the Great Bear ...

A nova 3,000 light-years away is due to become visible from Earth. T Coronae Borealis could be visible to the naked eye in the coming weeks. A few tips can help you see this cosmic burst, which will ...

Astronomers have put together the first three-dimensional reconstruction of an exploding star (known as a supernova). Using the European Southern Observatory's Very Large Telescope, they looked at ...

Earth was showered by radioactive debris from supernovae - exploding stars - as recently as 1.7 million years ago, research has shown. A series of stellar blasts are thought to have occurred around ...
