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 ...

A study suggests that Earth's crust in the Hadean eon, more than 4 billion years ago, was more similar to the modern continental crust than previously thought, with implications for the timing of ...

NASA’s Mars InSight has provided … well, insight, into the inner workings of the Red Planet. By monitoring “marsquakes” over the past two years the instrument has allowed scientists to measure the ...

In 1981, scientists discovered one of the thinnest portions of the Earth’s crust — a 1-mile (1.6 kilometers) thick, earthquake-prone spot under the Atlantic Ocean where the American and African ...

New research deepens the understanding of Earth's crust by testing and ultimately eliminating one popular hypothesis about why continental crust is lower in iron and more oxidized compared to oceanic ...

NASA scientists have found evidence that Mars’ crust is not as dense as previously thought, a clue that could help researchers better understand the Red Planet’s interior structure and evolution. A ...
