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 ...

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 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 ...

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 ...

A new study questions dark energy's role in the universe's acceleration, suggesting it may be weakening instead.

For the first time, astronomers have observed radio waves emitted by a Type Ia supernova, a type of explosion originating from a white dwarf star. This provides important clues to understand how white ...

Type Ia supernovae represent the dramatic thermonuclear explosions of white dwarf stars, typically triggered in binary systems by processes such as accretion from a companion or the merger of two ...

BERKELEY, CA -- By measuring polarized light from an unusual exploding star, an international team of astrophysicists and astronomers has worked out the first detailed picture of a Type Ia supernova ...

“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 ...

Ironically, to study dark energy — a murky, unknown something that seems to act as an accelerant for our universe’s expansion — astronomers rely on brilliant supernovae. From 2013 to 2019, the Dark ...

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 ...
