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 ...

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 ...

A new study shows that the so-called planetesimals that accreted together to form Earth must have been composed of dry, rocky materials. Billions of years ago, in the giant disk of dust, gas, and ...

Water has made the Earth the planet that it is—a planet known for its blue oceans. Water shapes the land through erosion and is fundamental to Earth’s ability to support life. But we have a hard time ...

Earth and Mars were formed from material that largely originated in the inner Solar System; only a few percent of the building blocks of these two planets originated beyond Jupiter’s orbit. A group of ...

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 ...

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 ...

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 ...

Tectonic map of the Earth. The first continental crust on Earth formed more than 3 billion years ago. Likely the first fragments formed by partial melting and re-crystallization of the primordial ...

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 ...
