Planetary scientists led by Paolo Sossi have determined that Earth assembled almost entirely from material originating in the ...

For years, planetary scientists have argued that some of the material that built Earth must have drifted in from beyond ...

Planetary scientists have long debated where the material that formed Earth comes from. Despite its location in the inner ...

A new analysis of meteorite isotopes challenges long-held ideas about Earth’s origins, suggesting our planet may have formed ...

Planetary scientists at ETH Zurich have shown that the material that makes up the Earth originates exclusively from the inner ...

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 interior ...

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...

Earth’s surface environment hosts large reservoirs of hydrogen (H, mainly in the form of water, H2O), nitrogen (in atmospheric N2) and carbon (mainly in carbonate rocks). H, N and C are sometimes ...

Continental clues: Modern continental rocks carry chemical signatures from the very start of our planet’s history, challenging current theories about plate tectonics. Researchers have made a new ...

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an instability of our planet's magnetic field. The two odd formations – one ...
