Huge Amounts of Helium Discovered in Earth’s Core, Changing What We Thought About the Planet’s Formation
For decades, scientists have puzzled over traces of primordial helium—a rare isotope known as ³He—escaping from volcanic ...
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 researchers were ...
Hot subdwarf stars represent a distinct class of compact, high-temperature objects that are predominantly core helium-burning and situated at the extreme end of the horizontal branch. These stars, ...
The diamond anvil crushed iron and helium together under conditions mimicking those inside the Earth, to create a new compound. These compounds remained stable when pressures were reduced. Further ...
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. When you purchase through ...
