Researchers have taken atomic diffraction to a new level, revealing surprising behaviors in high-energy helium and hydrogen ...

Hydrogen nano-clusters at low temperatures display 'superfluidity'—a quantum state of frictionless flow only previously observed in helium.

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.

Evans found that the 4686 series and the Pickering series can be obtained in a helium spectrum showing no trace of the ordinary hydrogen lines. These series were observed a few years ago by Prof.

“Before the first stars exploded, there was no water in the Universe because there was no oxygen. Only very simple nuclei ...

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 ...

By looking ever further back in time, the James Webb Space Telescope is at last revealing the first galaxies – and a very strange young cosmos ...

British researchers have found the key ingredient to life, water, might have been on Earth billions of years earlier than ...

Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

Helium normally has trouble bonding with other elements, but researchers were able to crush atoms of iron and primordial helium together at extremely high heat and pressure to bond them in a ...
