A small, seemingly technical assumption baked into the way astronomers standardize Type Ia supernovae may be responsible for the growing tension between different measurements of dark energy. New data ...

An artist’s illustration depicts silicon, argon and sulfur releasing from a massive star. - Adam Makarenko/W. M. Keck Observatory Astronomers have observed what they are calling a new type of ...

To date, there’s only sufficiently robust evidence for the existence of two classes of supernovae—that is, star explosions. But there have been plenty of signs that there are likely other types in the ...

SN 2024abfl, a low-luminosity Type IIP supernova in the galaxy NGC 2146. This rare find is shedding new light on how 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 ...

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 ...

Supernova 2018zd, marked with a white circle on the outskirts of galaxy NGC2146, is the first example of a new, third type of supernova predicted 40 years ago. Composite image with data from the ...

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 ...

EVANSTON, Ill. — 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 ...
