A collision between Earth and a massive Mars-sized protoplanet likely caused the formation of our moon. Now scientists from ...

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.

Earth formed around 4.54 billion years ago. Knowing how old Earth is can be more difficult to confirm because Earth's age is not only based on the age of rocks, but also the isotopic estimates of what ...

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 ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed. When you purchase through ...

Modern continental rocks carry chemical signatures from the very start of our planet's history, challenging current theories about plate tectonics. Researchers have made a new discovery that changes ...

Earth's early days The researchers built a new model of Earth's formation that considered both geochemical data and seismic data — the two main methods of peering into Earth's deep history. In ...

New research from Rice University suggests that the giant planet Jupiter reshaped the early solar system in dramatic ways, carving out rings and gaps that ultimately explain one of the ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. New model suggests an ocean of magma formed within the first few hundred million years of Earth's ...
