Deep inside Earth, researchers see signs that the solid inner core may be arranged in multiple chemical layers far below.

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from ...

Earth's inner core is solid and blistering hot. For decades, scientists have known the inner core is solid thanks to the pioneering work of Danish seismologist Inge Lehmann, who first proposed its ...

The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

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.

Gold and other precious metals are leaking from Earth’s core into the layers above, eventually making their way up to the surface during the formation of volcanic islands like Hawaii, a new study ...
