The Earth is four and a half billion years old, so why they started appearing then is unknown, as is the mechanism to make ...

Geologists studying some of the planet's oldest volcanic rocks have uncovered new evidence that water was playing a major ...

Water may have been shaping Earth’s deep interior far earlier than many geologists thought. In rocks more than 3 billion years old from Western Australia, a research team found chemical signs that ...

Water began to form the internal structure of the Earth and influence volcanic activity more than 3 billion years ago. This ...

There are several theories about how the Earth and the Moon were formed, most involving a giant impact. They vary from a model where the impacting object strikes the newly formed Earth a glancing blow ...

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.

Billions of years ago, in the giant disk of dust, gas, and rocky material that orbited our young sun, larger and larger bodies coalesced to eventually give rise to the planets, moons, and asteroids we ...

For many years, scientists have predicted that many of the elements that are crucial ingredients for life, like sulfur and nitrogen, first came to Earth when asteroid-type objects carrying them ...

Researchers at Curtin University have established a new framework for dating the Earth's evolution including the formations of continents and mineral deposits. The research, published in Earth Science ...

This is roughly what the formation of the Earth in our solar system might have looked like. The birth of two planets (light brown dots) in a protoplanetary disc around the young star WISPIT 2 ...

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 ...
