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 ...

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 ...

Type Ia supernovae represent the dramatic thermonuclear explosions of white dwarf stars, typically triggered in binary systems by processes such as accretion from a companion or the merger of two ...

Astronomers have discovered a new type of supernova, or star explosion, and it provides a new window into the violent life cycle of stars. The new research, focused on supernova 2018zd, confirms a ...

The result is a rare before-and-after look at a dying star. The supernova, called SN 2025pht, came from a red supergiant, one ...

A unique dataset of Type Ia supernovae being released today could change how cosmologists measure the expansion history of the universe. Dr. Mathew Smith and Dr. Georgios Dimitriadis from Lancaster ...

Cosmologists have found a way to double the accuracy of measuring distances to supernova explosions - one of their tried-and-true tools for studying the mysterious dark energy that is making the ...

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 ...
