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.

“Based on volcanic rock measurements, helium-3 is known to be enriched in hot magma, which originally derives from hot plumes coming from deep within Earth’s mantle.” The mantle is the region between ...

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

Primordial helium from the beginning of the solar system may be stuck inside Earth's solid core, new research suggests ... crust is pulling apart and out of volcanic hotspots that tap magma from the ...

The mantle contains both magma, or molten rock, and slowly-moving solid rock. Earth's innermost layer is called the core. The outside of Earth's core is made from molten nickel and iron that can ...

The Earth is made of different layers: the core, mantle and crust ... The upper mantle is hard but below that is semi-molten rock called magma. Crust The crust is the outer layer of the Earth ...

Primordial helium from the beginning of the solar system may be stuck inside Earth's solid core, new research suggests ... out of volcanic hotspots that tap magma from the deep mantle.

Wednesday March 26 – New research led by a York University professor sheds light on the earliest days of the earth’s formation and potentially calls into question some earlier assumptions in planetary ...
