For the first time, geologists have compiled a global map of the wave-like motions called “convective currents” inside Earth’s mantle. They found that those convective currents are moving roughly ten times faster than previously thought. The discovery can help explain everything from how Earth’s surface changes over…
Humans have dreamt of of drilling to the center of the Earth for over a century, but the fact of the matter is, we haven’t made it past the crust. An ambitious new scientific expedition hopes to change that.
In an unprecedented $1 billion mission to reach the Earth's mantle, geologists are set to start drilling 3.7 miles (6 km) beneath the seafloor, to reach the Earth's mantle. And according to project co-leader Damon Teagle, "It will be the equivalent of dangling a steel string the width of a human hair in the deep end…
If you're currently living on our pale blue dot, you should thank it for becoming inhabitable for us human folk. Specifically, you should look down and thank its mantle because scientists are saying that Earth's cooler mantle allowed it to develop oxygen. You know, that thing we breathe to live.
The Moon is an almost completely still world, its eternal peace and quiet disrupted only by the occasional meteor or Apollo astronaut. But we now know there's plenty of magma inside the Moon. So why are there no volcanoes?
Earth runs on massive amounts of heat, enough to melt iron in the core and create our magnetic field, enough to power the constant movement of plate tectonics. Where all this heat comes from is a mystery...but we're getting closer.
The inner core of our planet is roughly as big as the Moon, and we can only guess what's going on deep inside our planet. We might now have an answer...and it's even more volatile and weird than we thought.
Earth's continents are constantly changing, moving and rearranging themselves over millions of years - affecting Earth's climate and biology. Every few hundred million years, the continents combine to create massive, world-spanning supercontinents. Here's the past and future of Earth's supercontinets.
Nearly a mile underground, there's an entire ecosystem carving out a rather alien existence in the deepest layer of Earth's crust. These bacteria are totally unlike their brethren nearer the surface, and there might be even stranger bacteria further down.
1800 miles underground lies a mysterious zone between the Earth's mantle and core. Nobody is quite sure what's down there, but new evidence suggests the area reaches temperatures of 7000 degrees Fahrenheit, meaning it could be a vast magma ocean.
Earth formed 4.54 billion years ago. But we've never found any rocks remaining from the time when our planet formed. Until now. A piece of ancient mantle is revealing Earth's oldest secrets.
The Chikyu research vessel is already the world's deepest drill, probing nearly 23,000 feet beneath the ocean floor. But scientists hope to add another mile to the machine by 2013, allowing it to pierce Earth's mantle for the first time.
