Earth’s Magnetic North Pole Is Shifting Toward Siberia and Raising Questions About Unusual Movement
Scientists released an update to a model that maps the ever-moving pole and has significant implications for navigation systems
Largest Diamond Since 1905 Unearthed by Miners in Botswana
Volcanic eruptions long ago brought the 2,492-carat diamond—the latest in a string of stunning discoveries over the last decade—to the surface
Scientists Drill Deeper Into Earth’s Mantle Than Ever Before, Probing for the Origin of Life on Earth
The record-setting rock samples will provide insight into the chemical processes that may have kick-started life on our planet
Earth’s Inner Core May Be Slowing Its Spin, Another Study Suggests
New research adds evidence to the controversial idea that the hot, solid ball at the center of our planet has been reducing its speed for years as part of an oscillating cycle
Earth’s Magnetic Field Nearly Collapsed 600 Million Years Ago. Then, Weird and Complex Life Evolved
A new study suggests more solar radiation reached Earth while the magnetic field weakened, leading to a rise in oxygen that drove an explosion of multicellular organisms during the Ediacaran Period
Melting Polar Ice Sheets Are Slowing Earth’s Rotation. That Could Change How We Keep Time
As ice melts into water and flows toward the equator, it redistributes mass around the Earth, affecting the planet’s spin, a new study finds
Mars’ Core May Be Smaller Than Thought, Wrapped in a Sea of Molten Rock
Based on seismic waves from a meteorite impact, two teams of scientists suggest the Red Planet has another layer deep beneath its surface

The metal-rich object could hold clues about how our planet formed
Scientists Find Evidence of Another Core Within Earth’s Center
The newly proposed layer might have a different structure from the rest of the inner core
The Spin of Earth’s Inner Core May Be Changing, Scientists Say
A new study finds our planet’s iron center shifts between spinning slightly faster and slightly slower than the surface—but not all experts agree
