BERKELEY, CA — A group of scientists affiliated with the SuperNova Legacy Survey (SNLS) have found startling evidence that there is more than one kind of Type Ia supernova, a class of exploding stars ...

Supernovae, categorized as Type I (low hydrogen) and Type II (high hydrogen), produce varying abundances of heavy elements. Type Ia supernovae, resulting from thermal runaway in white dwarfs, are rich ...

The exploding stars known as Type Ia supernovae serve an important role in measuring the universe, and were used to discover the existence of dark energy. They’re bright enough to see across large ...

A team of astronomers led by The University of Texas at Austin’s Howie Marion has detected a flash of light from the companion to an exploding star. This is the first time astronomers have witnessed ...

“The explosions of white dwarfs play a crucial role in astronomy,” said Priyam Das, a study co-author and PhD student at the University of New South Wales Canberra, Australia. “Yet, despite their ...

The new paper argues that, in SN 1181, the first phase of the supernova fizzled out and left behind an unusually active ...

Astronomers know that when a star runs out of fuel and reaches the end of its life, it may go through an epic final stage in which it explodes in a tremendous output of energy called a supernova. But ...
