Which atoms make up most of the stuff in the universe? About 98% of the mass of the universe is made up of only two types of atoms: hydrogen and helium. That’s because these two elements make up stars ...

According to the laws of quantum mechanics, this diffraction is only possible because the energy exchange between graphene and the hydrogen/helium atoms is undetectable. Speaking with New ...

The atoms of some elements like helium do not form bonds. Helium atoms are single atoms. The atoms of elements such as hydrogen, nitrogen and oxygen join in pairs to make molecules. Water is ...

Carbon, which is found in the human body, takes an unusual journey after the demise of the the stars that create the element.

Recent advancements in this field have pushed the boundaries of what was once thought possible, demonstrating diffraction of high-energy helium and hydrogen atoms through single-layer graphene.

In a star like the Sun, four atoms of hydrogen eventually combine via fusion to make a heavier nucleus of helium. What makes fusion inside a star so useful is that the transformation of a light ...

Atoms forged in stars take a gigantic meandering ... All elements (other than hydrogen and helium) are formed in stars – in most cases during dramatic deaths. On realizing this, astronomers ...

Helium is notoriously hard to contain because, like hydrogen, it is a tiny little atom even by atomic standards. It also expands about 750 times when it turns into a gas, according to the post’s ...

This achievement takes the reactor into its operational phase, bringing us closer to clean and limitless energy using nuclear ...
