From the summit of Mount Everest to the depths of the Mariana Trench, Earth’s surface reveals dramatic extremes. This video ...

Over 4.6 billion years ago, Earth took shape from a spinning cloud of dust and gas surrounding the young sun. Tiny particles within this cloud collided and clumped together, driven by gravity and ...

New research shows how RNA, a key molecule for life, may have formed on early Earth using simple chemistry and materials delivered by asteroid impacts, linking space science with the origins of life ...

Remnants of a liquid layer of magma near Earth's core, formed in the first few hundred million years of the planet's history, may still persist today as odd anomalies in the mantle. When you purchase ...

New research is reshaping how scientists understand the earliest days of Earth’s formation—suggesting that the deep interior of our planet locked in its defining features just 100 million years after ...

Billions of years ago, in the giant disk of dust, gas, and rocky material that orbited our young sun, larger and larger bodies coalesced to eventually give rise to the planets, moons, and asteroids we ...

Scientists may finally be closing in on the origins of two colossal, mysterious structures buried nearly 1,800 miles inside Earth—hidden formations that have puzzled researchers for decades. New ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

How old is Earth? Our planet's age is known from a variety of sources, from rocks on our own planet to ones from the moon. When you purchase through links on our site, we may earn an affiliate ...

New research suggests that Theia, the object whose collision with Earth is theorized to have caused the formation of the moon, came from closer to the sun. Artist’s impression of the collision between ...
