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 within such a precise “Goldilocks zone” for oxygen that a 5% change would have prevented life from emerging.

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 ...

Planetary scientists Paolo Sossi and Dan Bower from ETH Zurich have published a peer-reviewed study in Nature Astronomy arguing that Earth formed almost entirely from inner solar system material, with ...

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 ...

About 4.6 billion years ago, the Solar System formed from a cloud of dust and gas collapsing in on itself due to gravity. The Sun, planets, and eventually Earth formed out of the cloud. But when did ...

The inner solar system may have formed differently from how we have long thought it must have. For decades, researchers have thought that the rocky planets formed from a single disc of dust and debris ...
