The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing ...

Earth formed around 4.54 billion years ago. Knowing how old Earth is can be more difficult to confirm because Earth's age is not only based on the age of rocks, but also the isotopic estimates of what ...

Earth is believed to have formed partly from carbonaceous meteorites, which are thought to come from outer main-belt asteroids. Telescopic observations of outer main-belt asteroids suggest that they ...

A study on the Earth's formation titled "Stochastic accretion of the Earth" has been published in the journal Nature Astronomy. Researchers from ETH Zurich have used a new modeling approach to ...

The James Webb space telescope has captured data that could help us better understand how Earth formed billions of years ago. According to the new data, James Webb has detected water vapor in ...

Around 4.6 billion years ago, a young, hot star was born. The Sun formed from a cloud of gas and dust, and over time planetary bodies, including Earth and Mars, came to be. It’s unlikely that ...

A vast ring of rocky leftovers between Mars and Jupiter, the asteroid belt preserves clues to how the planets — and Earth ...

Scientists have long believed that the Moon was formed by a massive object crashing into the Earth. But what was that thing ...

One key component might be RNA, a molecular cousin of DNA found in every form of life on Earth, and now scientists say they ...
