A Relentless Blitz Of Small Rocks Obliterated Earth's Early Atmosphere

The Earth went through some tough times after its formation 4.5 billion years ago. Geochemical evidence indicates that its atmosphere was obliterated at least twice. One theory is that a large object from space smashed into our planet's surface, but a new study suggests it was actually thousands of small impacts. » 12/02/14 1:20pm 12/02/14 1:20pm

An "Impenetrable Barrier" Protects The Earth From Killer Electrons

It appears that our planet's built-in force field is much stronger than we thought. Scientists studying the Van Allen belts have discovered the presence of a nearly impenetrable barrier that prevents some of the fastest and most powerful "ultrarelativistic" electrons from reaching the surface. » 11/27/14 1:00pm 11/27/14 1:00pm

Stunning Drone Footage From Beneath The Ice Of Antarctica

Scientists use a range of techniques—from satellite observations to drilling holes—to measure sea ice thickness. Usually, such efforts look down at the sea floor. But, by equipping an underwater drone with upward-looking sonar, researchers were able to create the first high-resolution 3D maps of Antarctic sea ice. » 11/25/14 2:40pm 11/25/14 2:40pm

Here's Awe-Inspiring Evidence for One of the Planet's Biggest Floods

About 15,000 years ago, as the latest ice age was winding to a close, glaciers that covered Canada began to melt. Then, one day, those shrinking glaciers unleashed the waters of a lake the size of Lake Huron, which scoured the land from Montana to the Pacific coast. Here's what we know of the great Ice Age flood. » 10/14/14 1:27pm 10/14/14 1:27pm

These Are The 100 Most Interesting Geologic Spots In The British Isles

The United Kingdom and Ireland pack so many geologically fascinating locations in a small area, it's hard to pick which ones are the most gorgeous, the most scientifically important, or even the most downright useful. Lucky for us, the Geological Society curated a list of the Top 100 Geosites. » 10/14/14 12:58am 10/14/14 12:58am
