Earth’s oxygenated atmosphere and magnetic field make life possible, but scientists have discovered that there’s a hidden ...

Earth's magnetic field originates in the outer core and extends out into the magnetosphere — a region of space that helps protect Earth from space weather.

The Earth's magnetic field is generated within the liquid core of our planet, by the slow churning of molten iron. Like the atmosphere and oceans, the way in which it moves is governed by the laws ...

Scientists convert Earth's magnetic field collapse from 41,000 years ago into chilling audio, revealing ancient cosmic ...

Every breath we take in contains 21% oxygen, the gas that makes life on Earth possible. Oxygen, in its combined oxide state, ...

Extending from Earth like invisible spaghetti is the planet's magnetic field. Created by the churn of Earth's core, this field is important for everyday life: It shields the planet from solar ...

The oldest firm age yet for Earth's magnetic field suggests that it developed before a solid planetary core, 3.7 billion years ago. When you purchase through links on our site, we may earn an ...

The Earth's magnetic field is essential to life as we know it. But it’s something we can never see – or hear, until now. In a recent study released on Oct. 10 by the European Space Agency, ...

In 2013, the ESA launched three Swarm satellites for a mission to help decode how Earth’s magnetic field is generated by precisely measuring the radiofrequency signals coming from the planet’s ...
