Deep beneath our feet, approximately 2,890 kilometers underground, lies one of Earth's most mysterious regions. The boundary between our planet's molten outer core and solid mantle acts like a massive ...

Earth's inner core, the solid iron-rich mass at the center of our planet, is slowly growing as the surrounding molten outer core cools and freezes. But this process has been a source of debate amongst ...

As early as 2024, scientists from the US and China discovered that the Earth’s core had slowed down and even stopped moving in relation to the Earth’s crust. But until now, the general public—that’s ...

The solid inner core at the center of the Earth, surrounded by the outer core, mantle and crust. Here’s why: While it is well known that a material must be at or below its freezing temperature to be ...

What is the speed and timing of the Earth’s inner core cooling? This is what a recent study published in Nature Communications hopes to address as a team of scientists investigated the composition ...

Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged ...
