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.

I asked my friend Julie Ménard how Earth formed. She’s a planetary scientist at Washington State University. She told me it started with the Big Bang. That was nearly 14 billion years ago. “The Big ...

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

As much as 45 oceans’ worth of hydrogen may be in Earth’s core, scientists reported, suggesting most of Earth’s water was ...

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’ ...

NASA says Earth is about halfway through its lifespan. Scientists explain how solar changes could affect habitability, oceans, and the planet’s future over billions of years ...

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

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 ...

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 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, funded by the NASA Lunar Science Institute (NLSI), theorizes that our early Earth and moon were both created together in a giant collision of two planetary bodies that were each five ...

A peculiar property of the Earth's magnetic field could help us to work out how our planet was created 4.5 billion years ago, according to a new scientific assessment. There are several theories about ...
