There may be hidden layers to Earth’s core dictated by chemical composition. In A Nutshell Lab experiments suggest Earth’s ...

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.

Astronomers have identified a wildly distorted world that looks less like a sphere and more like a squeezed citrus fruit, and ...

Researchers in England believe carbon played a key role in freezing Earth’s core. As it contributes to the cooling and freezing of the molten outer core, the solid, iron-rich center of Earth continues ...

Astronomers say they have spotted, for the first time, what appears to be the exposed core of a gas giant planet that has shed -- or never found -- its gaseous atmosphere. A team lead by the ...

A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle (the layer between a planet’s core and crust). For decades, scientists argued that hit-and-run ...

The early years of our solar system were a period of unimaginable chaos and violence, a gravitational free-for-all where colliding planetary embryos competed for survival. In this tumultuous ...

BepiColombo will arrive in 2026 to uncover the planet Mercury, and unravel how a planet as small, dense, and in such an odd ...
