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

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 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.

Scientists believe the new star covered in helium-burning ash is the result ... Josh Hawkins has been writing for over a decade, covering science, gaming, and tech culture. He also is a top ...
