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 ...

For decades, helium has been produced with natural gas, generating huge carbon emissions. Now, geologists are looking for new helium sources — and finding enormous "carbon-free" reservoirs that could ...

Scientists have coaxed one of the universe’s most stubborn elements into a new compound. Formed under intense pressures, the newly discovered compound packs helium atoms into crystalline iron, ...

New seismic data show that a helium reservoir discovered in February in northern Minnesota is larger than initial estimates indicated, inching the project closer to commercial extraction. When you ...
