For almost a century, we have known that the universe is expanding. For several decades, evidence has suggested that the ...

As if dark energy weren't already mysterious and baffling enough, new research suggests that this unknown force may not be ...

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 ...

"Remarkable" findings from Yonsei University cast doubt on 'dark energy' theory and claim there is "no evidence" of an ...

The universe's expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously ...

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 ...

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 ...

Researchers used type Ia supernovae, similar to SN1994d pictured in its host galaxy NGC4526, to help establish that the ...

May 8 (UPI) --The discovery of Type Ia supernovae with hydrogen, a rarity, could help astronomers trace the origins of the explosive cosmic phenomena. Type Ia supernovae occur when the white dwarf in ...

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 ...

Ever since Edwin Hubble's 1929 discovery that the universe is expanding, astronomers have known that the more distant a galaxy, the faster it's traveling away from us. They've long wondered to what ...
