A Type II supernova has been documented for the first time. This space achievement is a big deal since it can help astronauts and other experts to understand dying stars better. This NASA image shows ...

Astronomers have their eyes on a new ultrabright explosion in space: a Type II supernova in the Pinwheel Galaxy (also known as M101). A Type II supernova is the catastrophic end to a massive star's ...

Supernovae, categorized as Type I (low hydrogen) and Type II (high hydrogen), produce varying abundances of heavy elements. Type Ia supernovae, resulting from thermal runaway in white dwarfs, are rich ...

Physicists have a new theory on the mysterious mechanism that causes the explosion of massive, or core, stars. These type II supernovae, which are exploding core stars, are huge and spectacular events ...

Astronomers have found evidence that proves a 40-year-old supernova theory correct and a mysterious sky event that occurred in 1054 AD. A new study has been published in Nature Astronomy and outlines ...

The visible universe is a big place. Like, really, really big — some 93 billion lightyears across (via Futurism). To put that in perspective, that's like running 25 billion back-to-back marathons, and ...
