"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 ...

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

They went through the isotope mixtures in Earth and lunar rocks instead of using highly technical models. They dabbled in which compositions and sizes of Theia and which composition of the early Earth ...

For decades, scientists have held to the idea that the Moon was formed by a single, massive impact between Earth and a ...

Apollo samples provide evidence: Researchers analyzed Moon rocks brought back by the Apollo missions and, for the first time, used their iron isotope ratios to trace where Theia originally formed.

"The most convincing scenario is that most of the building blocks of Earth and Theia originated in the inner solar system. Earth and Theia are likely to have been neighbors." Over 4.5 billion years ...

Conventionally, the moon is thought to have formed during one big impact, but a three-impact model might make more sense ...

HONOLULU (KHON2) — Scientists continue to explore the deep story of how Earth and the moon formed. One idea has gained attention because it pushes us to imagine the planet in its earliest and wildest ...

Over 4.6 billion years ago, Earth took shape from a spinning cloud of dust and gas surrounding the young sun. Tiny particles within this cloud collided and clumped together, driven by gravity and ...

Whether it’s under the stars on the Main Green, from smudged dorm windows or through open sunroofs, we see the moon nearly every night. But a new study by Brown researchers suggests that we know less ...

Earth is so far the only known planet on which life exists—with liquid water and a stable atmosphere. However, the conditions were not conducive to life when it formed. The gas-dust cloud from which ...

Scientists continue to explore the deep story of how Earth and the moon formed. One idea has gained attention because it pushes us to imagine the planet in its earliest and wildest days.
