Scientists have identified a never-before-seen supernova, SN2021yfj, which exploded after losing nearly all of its outer layers. Instead of light elements, it revealed silicon and sulfur from deep ...

Researchers say the "powerful engine" behind superluminous exploding stars had been hidden for years — until a "chirp" from the cosmos helped confirm their link.

For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the ...

A rare gravitationally lensed supernova could help astronomers determine how fast the universe is expanding and shed light on dark energy. Astronomers may be closer to understanding one of the ...
