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 ...

Scientists have detected signatures in ancient rocks that push back the timeframe for the discovery of early life by billions of years.

Between 1.8 and 0.8 billion years ago, Earth's continents assembled and broke apart twice, first forming Nuna, then Rodinia. Using a new plate tectonic model covering 1.8 billion years of Earth's ...

The new approach looks at the distribution of molecular fragments in material, allowing for broad surveys in degraded ...

Scientists believed that the first complex life on Earth formed 635 million years ago, but new evidence suggested otherwise. It pushed back the origins of life to 2.1 billion years ago, 1.5 billion ...

Earth's earliest life left behind very few chemical traces. Fragile remains, like ancient cells and microbial mats, were buried, squeezed, heated, and broken apart by the planet's shifting crust ...

A machine-learning-enhanced approach to chemical analysis is drastically expanding the chemical record of life on Earth, and ...

Washington, DC— Pairing cutting-edge chemistry with artificial intelligence, a multidisciplinary team of scientists found ...
