In 1181 AD, a bright "guest star" was observed to linger in the sky for around six months. Nearly 850 years later, the likely ...

While we understand the basic concept behind supernovae to be the final energetic stage of stellar life, there are a ton of pressing questions that continue to riddle astronomers’ minds about how they ...

Supernovae are stellar explosions of cosmic proportions (literally). They are some of the most violent events in the known universe. A single supernova emits enough energy to outshine an entire galaxy ...

Giant stars die a violent death. After a life of several million years, they collapse into themselves and then explode in what is known as a supernova. How these stars explode remains a mystery.

Scientists have begun to unravel the mysteries behind a star's dying moments. Using a new 3D computer model, researchers were able to reconstruct what happens before a star explodes. Supernovae are ...

(Nanowerk News) Appearing ten to a hundred times brighter at its peak, and with a much faster rise toward the peak, stellar explosions AT 2018cow (nicknamed the COW) and SN 2018gep (nicknamed the GEP) ...

After eluding scientists for decades, observations from a nearby galaxy are providing evidence for a previously theoretical supernova model. Evidence of a new electron-capture supernova supports a ...

The death of a massive star is among the most energetic events in the cosmos. However, the particular way a star explodes is a matter of some dispute: different theoretical models predict different ...

The mysterious first moments of a supernova have now been modeled in 3-D—showing what happens in a dying star's heart from half a second to about two hours after the blast begins. The development ...
