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 like our sun and most of the stars in the universe.

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 ...

Space is home to a great many oddities, and even chemistry gets strange out there. In fact, there are even some molecules ...

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 ...

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

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 ...

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 ...

The Sun is a giant ball made of hydrogen and helium gases. Deep in the center of the Sun, hydrogen atoms are pressed together ...

Instead, all that energy is created through a nuclear reaction, which slams hydrogen atoms together to create larger helium atoms and some extra energy on the side. So even if you managed to ...

Approximately 13.8 billion years ago, the universe originated from a singularity, swiftly expanding and cooling to create the ...

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 ...
