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 ...

A fresh look at past data reveals that exoplanets with masses similar to Jupiter formed much sooner than previously thought, according to new research. The Ohio State University study's results ...

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 ...

Earth and Mars were formed from material that largely originated in the inner Solar System; only a few percent of the building blocks of these two planets originated beyond Jupiter’s orbit. A group of ...

Researchers investigate the effects of oxygen content on the melting of mantle rocks and the formation of early Earth magma It is widely accepted that the early Earth largely consisted of molten magma ...

Computational modeling shows that plate tectonics weren't necessary for early continents. The formation of Earth's continents billions of years ago set the stage for life to thrive. But scientists ...

A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.
