Tiny supernova mistake might erase the dark energy crisis, study says
A small, seemingly technical assumption baked into the way astronomers standardize Type Ia supernovae may be responsible for ...
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 ...
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 ...

Dark energy: did the universe quietly loosen its grip on acceleration?
Two-sigma things happen all the time. But three sigma I’m listening now. Dragan Huterer Dark energy has been the most ...
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 ...
Until now, supernovas came in two main “flavors.” A core-collapse supernova is the explosion of a star about 10 to 100 times as massive as our Sun, while a Type Ia supernova is the complete disruption ...
The universe often behaves in human-like ways. Gluttonous stars can swallow too much material and end up exploding in a rather dramatic fashion. NASA’s Chandra X-ray observatory recently caught a ...
A team of astronomers has discovered the fastest optical flash of a Type Ia supernova. A team of astronomers has discovered the fastest optical flash of a Type Ia supernova, and reports a study in the ...
Berkeley Lab astrophysicist Peter Nugent, working with Adam Riess of the Space Telescope Science Institute, used an IBM SP supercomputer at NERSC to analyze data from an exploding star that had been ...
