Astronomers have proposed a new theory to explain the origin of phosphorus, one of the elements important for life on Earth. The theory suggests a type of stellar explosion known as ONe novae as a major source of phosphorus.

After the Big Bang, almost all of the matter in the Universe was comprised of hydrogen.

Other elements were formed later, by nuclear reactions inside stars or when stars exploded in events known as novae or supernovae.

But there are a variety of stars and a variety of ways they can explode.

Astronomers are still trying to figure out which processes were important in creating the abundances of elements we see in the Universe.

In this study, Kenji Bekki, at The University of Western Australia, an...

Outflowing galactic winds from exploding stars may explain the enormous rings. Astronomers believe they may have found the origin of the universe’s giant odd radio circles: they are shells formed by outflowing galactic winds, possibly from massive exploding stars known as supernovae.

t’s not every day astronomers say, “What is that?” After all, most observed astronomical phenomena are known: stars, planets, black holes and galaxies...

A new way to simulate supernovae may help shed light on our cosmic origins. Supernovae, exploding stars, play a critical role in the formation and evolution of galaxies...

New study offers hope to long-standing scientific problem. In a new study, researchers have taken an important step toward understanding how exploding stars can help reveal how neutrinos, mysterious subatomic particles, secretly interact with themselves.

One of the less well-understood elementary particles, neutrinos rarely interact with normal matter, and instead travel invisibly through it at almost the speed of light. These ghostly particles outnumber all the atoms in the universe and are always passing harmlessly through our bodies, but due to their low mass and lack of an electric charge they can be incredibly difficult to find and study.

But in a study p...
