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.

Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t pose a threat to life Earth’s magnetic field surrounds the planet, with ...

In the late 1800s, the French naturalist Camille Viguier proposed an idea that would be dismissed and forgotten for more than a century. He speculated that birds and other animals could navigate with ...
