"Why are we here?" is humanity's most fundamental and persistent question. Tracing the origins of the elements is a direct attempt to answer this at its deepest level. We know many elements are ...

These models are then integrated into a galactic chemical evolution pipeline to examine how successive generations of supernova explosions accumulate heavy elements and contribute to the formation of ...

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.

In the culmination of a decade's worth of effort, scientists analyzed an unprecedented sample of more than 1,500 supernovae classified using machine learning. They placed the strongest constraints on ...

For nearly a century, astronomers have known that the universe is expanding. In the late 1990s, two independent teams, the ...

When a star explodes at the end of its lifetime, it smears the elements forged in its heart across vast stretches of space. The results, dramatic designs of gas and dust known as supernova remnants, ...

Researchers have found white dwarf stars with masses close to the maximum stable mass (called the Chandrasekhar mass) are likely to produce large amounts of manganese, iron, and nickel after it orbits ...

Researchers have found white dwarf stars with masses close to the maximum stable mass are likely to produce large amounts of manganese, iron, and nickel after it orbits another star and explodes.
