New research led by a York University professor sheds light on the earliest days of Earth's formation and potentially calls ...

“This argument suggests that helium-3 was incorporated into the iron-rich core during Earth’s formation, some of which leaked from the core to the mantle,” Hirose explains. It could be that the ...

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.

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.

A newly found super-Earth could help provide answers as to why there are hardly any planets twice the diameter of Earth.
