Earth's diameter is about 7,900 miles. 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.

Researchers from Japan and Taiwan reveal for the first time that helium, usually considered chemically inert, can bond with ...

The discovery that inert helium can form bonds with iron may reshape our understanding of Earth’s history. Researchers from ...

Neutrinos generated through solar fusion reactions travel effortlessly through the sun's dense core. Each specific fusion ...

They used a laser-heated diamond anvil cell to find this, and the discovery suggests there could be huge amounts of helium in ...

The Earth has a layered structure, including the core, mantle and crust. The crust and upper mantle are cracked into large pieces called tectonic plates. These plates move slowly, but can cause ...

In this way, something 'new' could be seen: "We found evidence that may indicate a change in the structure of iron, suggesting perhaps two separate cooling events in Earth's history." It should be ...

Turbidity currents are an important natural process that often goes unnoticed: these powerful currents beneath the ocean surface carve deep submarine canyons, create huge sediment deposits and can ...

Using seismic stations usually used for monitoring earthquakes, an international team of geoscientists tracked Earth’s ...

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an ...

The study of seismic waves provides evidence for the internal structure of the Earth, which cannot be observed directly. P waves are detected on the opposite side of the Earth. Refractions between ...
