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 ...

Many stars die spectacularly when they explode as supernovae. During these violent explosions, they leave behind thick, ...

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 ...
