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 research team from the Yunnan Observatories of the Chinese Academy of Sciences (CAS), in collaboration with domestic and international partners, has carried out observational studies on SN 2024gy—a ...

A unique dataset of Type Ia supernovae being released today could change how cosmologists measure the expansion history of the universe. Type Ia supernovae are the dramatic explosions of white dwarf ...

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 ...

A type Ia supernova occurs when a white dwarf — the cooling remnant of an aging star — draws hydrogen from a companion sun. When the dwarf reaches 1.4 times the mass of the Sun, the star spontaneously ...

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 ...

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 ...

NASA has released an unprecedented time-lapse video showing the evolution of Kepler’s Supernova Remnant, a cosmic relic of a massive stellar explosion. Captured by the Chandra X-ray Observatory over ...
