According to a recent study, published inScience Advances, the early Earth was formed astonishingly fast, but it wasn’t initially a planet capable of supporting life. The building blocks of biology, ...
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.
One of the oldest unsolved riddles in planetary science concerns the origin of the moon. Over a century ago, George Darwin ...
About 4.6 billion years ago, the Solar System formed from a cloud of dust and gas collapsing in on itself due to gravity. The Sun, planets, and eventually Earth formed out of the cloud. But when did ...
The giant protoplanet Theia, which collided with Earth 4.5 billion years ago, originated from the inner solar system and likely formed closer to the sun than Earth. This was discovered by a research ...
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 ...
One bright day on Earth about 4.5 billion years ago, everything changed. A massive object slammed into the young planet. The impact was so large that bits were flung out into space, eventually ...
New research suggests Earth's Moon formed from the catastrophic collision of our planet with its "sister" planet, Theia, born nearby. This "sibling" planet theory, supported by iron isotope evidence, ...
The Moon's real age, and creation from the collision of Earth and Theia, finally confirmed (Updated)
A new study has determined with 99.9% accuracy that the Moon was formed 95 million years after the birth of the Solar System. This pegs the Moon as being a lot younger than we previously thought -- ...
Seismic imaging has exposed two massive zones hidden deep in Earth’s mantle. These giant blobs, known as large low-velocity provinces, or LLVPs, stretch beneath Africa and the Pacific. They are so ...
Earth has never stood still. Over its 4.5 billion years of history, our planet has been reshaped by different cataclysms and climate shifts. The atmosphere went through several changes, oceans froze ...
