Over 4.6 billion years ago, the early Earth emerged from a swirling disk of gas and dust encircling the young sun. This ...

When the early Earth’s magma ocean crystallized 4.4 billion years ago, the deep mantle trapped an ocean’s worth of water, ...

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 ...

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 ...

One key component might be RNA, a molecular cousin of DNA found in every form of life on Earth, and now scientists say they ...

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 ...

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 ...

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 ...

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 ...
