A new NASA study reveals a surprising way planetary cores may have formed—one that could reshape how scientists understand the early evolution of rocky planets like Mars. Conducted by a team of ...

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 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.

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 ...

CAPE CANAVERAL, Fla. (AP) — Scientists revealed Wednesday that Mars’ innermost core appears to be a solid hunk of metal just like Earth’s. The Chinese-led research team based their findings on seismic ...

The cars, cellphones, computers and televisions that people in the U.S. use every day require metals like copper, cobalt and platinum to build. Demand from the electronics industry for these metals is ...

Astronomers have identified a wildly distorted world that looks less like a sphere and more like a squeezed citrus fruit, and it is rewriting what I thought I knew about how planets form and survive.
