Buried more than 3,000 miles beneath our feet, Earth’s solid inner core was once thought to be unchanging—locked in place at the heart of the planet. But new research has revealed something much more ...

Researchers have found evidence of changes in the structure of the Earth’s core. University of Southern California team, led ...

The Earth has a layered structure made ... heat energy from the hot core. The outer core is liquid iron and nickel and generates the Earth's magnetic field. And the inner core is made of solid ...

A deep learning-based scheme is proposed for automated and efficient processing of teleseismic phases. 1. The validation with ...

The Earth's interior is composed of four layers ... in diameter. Although this inner core is white hot, the pressure is so high the iron cannot melt. The iron isn't pure—scientists believe ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously, its ...

Over time, Earth's interior—which is made mostly of silicate rocks and metals—differentiated into four layers. At the planet's heart lies the inner core ... to the field's structure, some ...

The next layer is the mantle, which makes up most of Earth's volume and is composed of dense, semi-solid rock. Then there is the outer core, made of liquid metal, and the inner core, a solid ball ...

Just as earthquakes help us study Earth's interior, starquakes reveal what lies beneath a star's surface. Each star "sings" a melody, with frequencies determined by its internal structure and ... has ...
