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.

Old crystals found in Western Australia are drawing fresh attention from geologists studying how the planet first took shape.

Earth’s core has often been described as just a giant ball of iron and nickel. Now, a new study argues that it is also a major storage place for hydrogen, possibly equivalent to dozens of oceans’ ...

Scientists suggest that huge reserves of hydrogen inside the Earth may have been key in the formation of water.

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.

A new scientific revelation reveals that deep in the Earth’s core lies a good amount of hydrogen as well as a large amount of iron. While the iron in the core has always been recognized as dominant, ...

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

A study published in the journal Earth and Planetary Science Letters posits that Mars formed in what today is the Asteroid Belt, roughly one and a half times as far from the sun as its current ...

Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure ...
