The simulations showed that the gravity hole was initially much less pronounced. Between roughly 50 million and 30 million years ago, however, it intensified significantly. This period coincides with ...

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

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

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 vast “gravity hole” beneath Antarctica became stronger as the continent shifted into an ice-dominated world tens of ...

After accounting for Earth’s rotation, gravity is slightly weaker beneath Antarctica than anywhere else on the planet. That ...

F rom space, planet Earth looks like a perfect sphere. But it’s not. Obviously, the crust of the Earth is irregular, covered in jagged mountains and deep oceanic trenches, but even if it were ...

Researchers uncover how slow changes deep inside Earth created Antarctica’s gravity anomaly and may even connect to ancient ...

Forte and colleagues now believe Antarctica’s gravity hole was weaker before eventually intensifying around 30 to 50 million years ago. This corresponds to large-scale changes in the continent’s ...

NASA's Curiosity rover, which launched in 2011 from Florida, found signs of organic material that on Earth is most often ...

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 ...

Tiny zircon crystals are revealing that Earth’s earliest history may have included surprisingly complex tectonic activity.
