Chemistry in the first 50 million to 100 million years after the Big Bang may have been more active than we expected.

Astronomers have glimpsed the inner structure of a dying star in a rare kind of cosmic explosion called an "extremely ...

Astronomers have used a new type of extreme supernova in which a massive star was stripped right "down to the bone" to better ...

Astronomers have seen a lot of stars explode, but one unusual stellar death is forcing them to rethink what they thought they ...

Why has silicon, one of the most common elements in the universe, gone largely undetected in the atmospheres of Jupiter, ...

Stars have to make all the other elements in the universe in their nuclear fusion-powered cores.

Israeli and American scientists discovered a never-before-seen type of supernova, one that blasts out heavy elements like silicon and sulfur from the body of a dying star, a new study reveals.The ...

Most elements lighter than iron are forged in the cores of stars. A star's white-hot center fuels the fusion of protons, squeezing them together to build progressively heavier elements. But beyond ...

Stars begin their lives when hydrogen fusion ignites in their dense, hot cores. Once that process starts, it's game on. The gravitational pull of all the mass of the star tries to squeeze it down ...

Lead and other elements are produced when nuclear fusion in a star adds neutrons to the atomic nuclei of lighter elements.

These stars appear to be almost 'upside down,' one expert said, because elements typically within stars are on their surface.

In “The Star Builders,” Arthur Turrell explores the attempt to produce clean and abundant energy through nuclear fusion.
