Lead is at the center of one of Earth’s strangest mysteries. A big chunk of it is gone. Not just misplaced, but missing in a ...

Planetary scientists led by Paolo Sossi have determined that Earth assembled almost entirely from material originating in the ...

A new analysis of meteorite isotopes challenges long-held ideas about Earth’s origins, suggesting our planet may have formed ...

For years, planetary scientists have argued that some of the material that built Earth must have drifted in from beyond ...

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. A new study shows that Earth formed under ...

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 sheds light on the earliest days of the earth's formation and potentially calls into question some earlier assumptions in planetary science about the early years of rocky planets.

Planetary scientists have long debated where the material that formed Earth comes from. Despite its location in the inner solar system, they consider it likely that 6–40% of this material must have ...

Earth likely formed from inner Solar System material alone, raising fresh questions about the origin of water on our planet.

This is roughly what the formation of the Earth in our solar system might have looked like. The birth of two planets (light brown dots) in a protoplanetary disc around the young star WISPIT 2 ...
