Earth's magnetic field dramatically flipped roughly 41,000 years ago. Now you can actually 'hear' this epic upheaval, thanks to a clever interpretation of information collected by the European Space ...

Earth’s magnetic field, the invisible barrier that deflects solar radiation and makes surface life possible, is not permanent in its current orientation. Geologic records show that magnetic north and ...

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

Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s radiation at bay. Increasingly, though, scientists are finding that this ...

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, researchers ...

A stream of charged particles known as the solar wind flows from the Sun toward Earth. Here, it meets the Earth’s magnetic fields, which shield our planet like a giant umbrella. The Space Umbrella ...

About 41,000 years ago, Earth’s magnetic field briefly flipped in what is known as the Laschamp event. Now, a group of scientists using data from the European Space Agency’s (ESA) Swarm mission have ...

As Earth warms, much of the extra heat is stored in the planet’s ocean — but monitoring the magnitude of that heat content is a difficult task. A surprising feature of the tides could help, however.

A stream of charged particles known as the solar wind flows from the Sun toward Earth. Here, it meets the Earth's magnetic fields, which ...
