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’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 ...

Webb Telescope detects an atmosphere on TOI-561 b, a scorching rocky planet once thought too small and hot to hold onto its ...

The Earth’s inner core, predominantly composed of iron with a minor admixture of nickel and light elements, is a critical component in understanding our planet’s magnetic field and thermal evolution.

Researchers using NASA's James Webb Space Telescope have detected the strongest evidence yet for an atmosphere on a rocky planet outside our solar system.

Could the oldest rocks under our feet be the remains of a planet that is now extinct? This is the kind of question that ...

An ultra-hot rocky exoplanet may be wrapped in a dense atmosphere, defying expectations about what small planets can sustain.

It's safe to assume you can't breathe on the moon. You probably already guessed that. But not only is there no breathable air ...
