Astronomers have observed what they are calling a new type of supernova, which has provided an unparalleled glimpse into what happens deep within a star just before it explodes. A study detailing the ...

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 ...

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 ...

For over 30 years, astronomers have relied on Type Ia supernovae to measure the universe’s expansion. These stellar ...

Supernovas are bad news. They can wreck biospheres and flood planets with deadly radiation. And now, a recent study has added a new potential threat: a special type of supernova that can destroy a ...

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 ...

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 ...

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 ...

Just 150 light-years from Earth, a team of astronomers has identified an exceptional binary system. These two stars, separated by only 1/60th of the Earth-Sun distance, are on a collision course. This ...

November 5—The SciDAC program within DOE's Office of Advanced Scientific Computing Research supports High Energy and Nuclear Physics research in the use of terascale computers to dramatically extend ...
