A startup company wants to establish mining operations on the moon to extract a rare isotope needed for future quantum ...

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.

The team also used secondary ion mass spectrometry to determine the concentration of helium within their samples. “We also performed first-principles calculations to support experimental findings,” ...

Helium is one of the most abundant elements in the universe, second only to hydrogen, and makes up most of the mass in protoplanetary disks like the one from which our Solar System emerged.

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed. Primordial helium from the ...

For example, a helium atom has an atomic mass of 4, but an atomic number (or positive charge) of 2. Since electrons have almost no mass, it seemed that something besides the protons in the nucleus ...

01 times that of our own sun, but their mass is about the same. Stars like our sun fuse hydrogen in their cores into helium. White dwarfs are stars that have burned up all of the hydrogen they ...

This method likely prevented the escape of helium during the measurement phase, Hirose said in a statement. This artificially colored image made using a technique called secondary ion mass ...

Our planet’s core is made mostly of iron, but it might also contain primordial helium that formed just after the Big Bang. Helium normally has trouble bonding with other elements, but ...

Figuring out how helium-3 got incorporated into the core during Earth's formation is very important for understanding when the planet formed, Olson said. Light gases like helium hung around in the ...
