Astronomers have announced the discovery of what appears to be an "ice cold Earth," a chilly but potentially habitable rocky ...

Life on Earth may exist thanks to an incredible stroke of luck — a chemical sweet spot that most planets miss during their formation but ours managed to hit.

Learn about HD 137010 b, a cold Earth‑sized planet candidate that sits near the outer edge of its star’s habitable zone.

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’ ...

Earth’s magnetic field is constantly swirling and shifting thanks to a colossal ocean of liquid metal sloshing around in its belly, but perhaps there's more to the story. In a new study, geologists ...

SIGNS of an alien planet that’s about the same size as Earth have been picked by up a Nasa telescope. Scientists say it might ...

Scientists discovered plate anomalies in Earth's mantle using seismic wave analysis. These mysterious structures challenge tectonic theories.

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

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

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 ...

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 ...
