Our Moon was formed from a violent collision that occurred around 4.5 billion years ago. And the giant body that smashed into the Earth, birthing the planet’s natural satellite, was named Theia. A new ...

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 4.5 billion years ago, a planet called Theia is thought to have smashed into newborn Earth. The messy collision kicked up debris, which probably formed our nighttime companion, the moon. While ...

About 4.5 billion years ago, a colossal impact between the young Earth and a mysterious planetary body called Theia changed everything—reshaping Earth, forming the Moon, and scattering clues across ...

Long ago, our solar system lost a planet. The planet, which scientists have since named Theia, found itself barreling uncontrollably toward a young Earth. The resulting impact destroyed Theia, turned ...

Immediately after the proto-Earth was formed, the Lambda luminosity started pumping heat into the core. This gave rise to a heated equatorial belt in the outer core and the two antipodal proto-LLVPs.

Earth's first continents may have emerged from the planet's primordial oceans much earlier than we thought, just six hundred million years after the planet formed, new research suggests. The ...

A planet-forming disk with more water than all of Earth's oceans has been discovered. The disk, which is located in the constellation Taurus, is 450 light-years away from Earth. Astronomers used the ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

Modern continental rocks carry chemical signatures from the very start of our planet's history, challenging current theories about plate tectonics. Researchers have made a new discovery that changes ...
