What is the chemical composition of the Earth's interior? Because it is impossible to drill more than about ten kilometres deep into the Earth, volcanic rocks formed by melting Earth's deep ...

The bulk elemental composition of Earth can’t be fully explained by compositional differences in its initial building blocks, according to a new study by Paul Frossard and colleagues. Instead ...

Earth, meanwhile, is a rocky, layered planet covered by water and teeming with life. Nevertheless, the elemental composition of these two celestial bodies is surprisingly similar.

In this way, the researchers indirectly obtained information on the composition of the material in the Earth’s mantle: the isotope analyses showed that it contains far fewer rare Earth elements ...

Astronomers have discovered that the chemical structure of Earth-like planets can be very different from the bulk composition of Earth. This may have a dramatic effect on the existence and ...

ANU scientists produce the best estimate to date of Earth’s composition IT TURNS out there’s a lot we don’t know about our planet — and a new understanding is said to have “far-reaching ...

The planet-making disk should therefore initially have the same gas-to-dust ratio as the interstellar medium: about 100 to 1, by mass. Similarly, it seems logical that the elemental composition of the ...

The chemistry of the core drives our planet’s magnetic field and holds clues about Earth’s history. Geochemists are going to extremes to understand it ...

Everything has a beginning, and a new study finds that the start of life on Earth arrived in the form of melted asteroids. The new research from the United Kingdom traced the chemical fingerprints of ...

A new study examines the possibility that cosmic collisions may have knocked material off Earth, which could explain suspected discrepancies in the compositions of the planet's uppermost layers.
