"During the early solar system's game of cosmic billiards, Earth was struck by a neighbor,” said Dauphas. “It was a lucky shot. Without the moon's steadying influence on our planet's tilt, the climate ...

Roughly four and a half billion years ago the planet Theia slammed into Earth, destroying Theia, melting large fractions of Earth’s mantle and ejecting a huge debris disk that later formed the moon.

New research suggests that Theia, the object whose collision with Earth is theorized to have caused the formation of the moon, came from closer to the sun.

If you know any bit of information about how the moon was created, new research indicates that everyone has believed wrong.

Little is known about the long-destroyed moon-forming planet, Theia. But it may have been born in the inner solar system—just like Earth—a new study suggests ...

Earth and the planetary object that gave rise to the Moon were likely born in the same region of the solar system.

The formation of the Moon may have come harder on the heels of Earth's birth than we thought. According to a new analysis by researchers from the US, France, and Germany, Earth's constant companion ...

Scientists traced the Moon's parent planet Theia to the inner Solar System, solving a 4.5-billion-year mystery.

To our best of our understanding, the Moon formed from Earth following a colossal impact. A Mars-sized world we nicknamed Theia slammed and merged with the primordial Earth, throwing material into ...

Research into the formation of the moon was conducted by scientists at the Weizmann Institute of Science in Rehovot, Israel and the Technion-Israel Institute of Technology located in Haifa. Results of ...
