Researchers used atomic-scale computer simulations to discover the importance of carbon in forming a solid planetary core.

Geologists and planetary scientists are rethinking how Earth's continents may have formed after discovering that the leading theory may not be possible after all.

Earth is a wet planet that formed in a dry part of the solar system. How our planet’s water arrived may be a story of big, bullying planets and ice-filled asteroids.

How did the Earth and moon form? The Earth, like all the other planets in the solar system, started out its life as a disc of dust and gas orbiting the young sun. The dust particles were brought ...

Astronomers and geologists have several techniques for dating Earth, and, therefore, the age of the solar system. From the radiometric dating of rocks, which measures the known decay rates of ...

A researcher has concluded that life first emerged on Earth — despite an astronomically small probability of such an ...

We now know the Earth is around 4.5 billion years old, while the planet's core is about two years younger than that thanks to the time-dilating effects of gravity. But how did we figure that out?

Now, a new study published in Science Advances shows that a special group of molecules, known as peptides, can form more easily under the conditions of space than those found on Earth.

How did eastern North America form? Collisions hold lessons for how the edges of continents are built and change over time.

Efforts to determine Earth's age have a long history. The ancient Greek philosopher Aristotle believed that time was eternal and, consequently, that Earth was infinitely old.
