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 ...

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 ...

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 ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...

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 ...

A small but evolving dent in Earth’s magnetic field can cause big headaches for satellites. Earth’s magnetic field acts like a protective shield around the planet, repelling and trapping charged ...

Scientists have found the oldest direct evidence for tectonic motion on Earth by more than half a billion years ...

Check your compass again – Earth’s north magnetic pole is moving toward Siberia. Since at least the early 19th century, Earth’s north magnetic pole has been situated in the Canadian Arctic and slowly ...

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.

Here’s what you’ll learn when you read this story: It used to be thought that there were more volatiles than expected in lunar soil because they escaped Earth before it had a stable magnetic field.
