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 ...
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 ...
“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 ...
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 ...
Astronomers have identified the remains of a rare type of supernova in our home galaxy for the first time. These events, known as Type Iax supernovae, occur when white dwarfs explode and may leave ...
Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. This article is more than 4 years old. The Carina Nebula, with Eta ...
It’s easy to forget that stars, just like us, have lifetimes. They’re born, they live, and eventually, they die. And for some stars, their death is dramatic, producing an explosion so powerful it can ...
