Every winter, thousands of tourists travel to high-latitude regions like Scandinavia, Canada, and Alaska hoping to see the Aurora Borealis or Northern Lights. Vincent Ledvina, an aurora guide and Ph.D ...

Ice cores, tree rings, and satellite data converge on a striking truth: Earth’s rapid changes today are unlike anything seen in human history. When most people hear the term Earth science, they think ...

Scientists at Stanford have unveiled the first-ever global map of rare earthquakes that rumble deep within Earth’s mantle rather than its crust. Long debated and notoriously difficult to confirm, ...

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

Sediments from Scotland hint that ocean-atmosphere interactions continued more than 600 million years ago despite widespread ice.

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 ...

Even when Earth was locked in its most extreme deep freeze, the planet’s climate may not have been as silent and still as ...

Bates has welcomed a large group of new faculty this year. Seventeen tenured or tenure-track professors joined the college ...
