A study published in the journal Icarus showed the ingredients for water may have been present as early Earth was developing, indicating that the creation of water may be a more common process on ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began.

Using a rare type of meteorite, known as an enstatite chondrite, which has a composition analogous to that of the early Earth (4.55 billion years ago), they have found a source of hydrogen which ...

By tracking how these elements decay, scientists can reconstruct Earth’s early history. Their studies show that turning dust into planetesimals took tens of millions of years. The final stages ...

Earth and other rocky planets likely developed a primitive crust early on, but their chemical makeup hasn’t been studied much. This crust formed when materials from a vast magma ocean, created during ...

Did the chemical components necessary to create water on Earth come from space or already exist here? One prevailing notion holds that asteroids containing either water of its building blocks ...

Researchers say they have uncovered evidence that early Earth was home to more hydrogen than previously thought, calling into question widely held beliefs about the origins of water and the ...

Earth Day is celebrating its 55th anniversary this year. The environmental event is marked by an estimated one billion people across more than 190 countries, according to the Earth Day ...
