New research reveals the source of this carbon – and the driving forces behind it – are far more complex than previously ...

In the whole history of Earth's climate, few events are as extreme as those that geologists call "Snowball Earth." ...

NASA says Earth is about halfway through its lifespan. Scientists explain how solar changes could affect habitability, oceans, and the planet’s future over billions of years ...

Our Earth is structured sort of like an onion – it’s one layer after another. Starting from the top down, there’s the crust, which includes the surface you walk on; then farther down, the mantle, ...

Scientists have spent decades cataloging life on Earth’s surface, from rainforest canopies to ocean trenches. But a growing body of research now shows that a vast, hidden biosphere thrives kilometers ...

Earth’s core has often been described as just a giant ball of iron and nickel. Now, a new study argues that it is also a major storage place for hydrogen, possibly equivalent to dozens of oceans’ ...

A team of researchers has produced the strongest experimental evidence yet that Earth’s iron core holds enormous quantities ...

WASHINGTON, D.C. — Earth’s inner core, a solid metal ball gyrating within the molten outer core, may be both slowing down and changing shape. Recent analyses of earthquake waves have suggested that ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Earth’s core is pretty dynamic. Its spin speeds up and slows ...

Gravity feels reliable—stable and consistent enough to count on. But reality is far stranger than our intuition. In truth, the strength of gravity varies over Earth's surface. And it is weakest ...
