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 ...

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.

NASA-supported scientists have provided new information about how the early Earth may have acquired some elements necessary ...

When Earth first formed around 4.5 billion years ago, it was a ball of molten rock. Over time, heavier elements, like iron and nickel, sank to the planet's center, forming the Earth's early core.
