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.

Volcanic activity is increasing at Alaska's Mount Spurr volcano, which scientists say could indicate an eruption in weeks as ...

A massive 'gravity hole' pulling down the Indian Ocean has stumped scientists for years, but the mystery may have just been ...

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.

It was a respectable tenure, but the world’s oldest known meteorite site is no longer western Australia’s 2.2 ...

The planet's internal structure comprises four layers: a rocky crust on the outside, then a rocky mantle, an outer core made of magma and a solid inner core. This metallic inner core, about 1,500 ...

Today, the upheavals of plate tectonics continually reshape Earth. When this began is much disputed - and we can’t fully understand how life began to thrive on our planet until we figure it out ...

Add to the magma that in numerology, 2025 is a 9, a number associated with Mars, the red-hot warlord of drive, desire, and eruptions of the sexual and volcanic kind. Further, Mars, our planet of ...

which are the huge pieces of crust that fit together like puzzle pieces and cover the surface of the planet. At places where two tectonic plates are pulling away from each other, magma — hot, ...

One of the earliest hypotheses suggested that Earth's water was a direct byproduct of the planet's formation, released via magma during volcanic eruptions, in which most of the emitted gas is ...

Researchers from Curtin University have uncovered the world’s oldest known meteorite impact crater in Western Australia, ...
