Astronomers uncover the first direct evidence for how some white dwarf stars explode, confirming the long-debated ...

An unusual star system created more of a fizz and less of a bang when it exploded in a supernova. The “ultra-stripped” supernova led researchers to discover the two stars 11,000 light-years ...

This new supernova has appeared in a galaxy — a star city — beyond our own. The galaxy is known as the Pinwheel Galaxy, (also designated as Messier 101, or M101) and is a large, loosely wound ...

A sparkling new supernova has appeared in the night sky, and a telescope atop Mauna Kea in Hawaii was perfectly poised to capture the aftermath of the cosmic burst.

Astronomers recently discovered the remnant of a galactic supernova with a remarkable circular symmetry, making it stand out as one of the most perfectly spherical objects detected in the universe.

The most recent nearby supernova, SN 1987A, was in the Large Magellanic Cloud. The Milky Way’s youngest known supernova is called G1.9+0.3.

A first-of-its-kind, animated map has revealed fresh secrets about a mysterious, flowering "zombie star" lurking in the remnant of a supernova that lit up Earth's skies more than 800 years ago.

Without supernova explosions, life on Earth could look very different. Many things had to go just right for us to be here. Maybe in the distant past, supernova explosions played a role in the ...
