Titan, Saturn’s largest moon, possesses a thick, nitrogen-rich atmosphere that bears striking similarities to that of early Earth. Scientists are fascinated by Titan’s atmospheric composition and its ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began. A study ...

Manganese dioxide can convert amino acids into hydrogen cyanide (HCN) without requiring methane, a finding that solves a long ...

A recent study investigates how polyester microdroplets, potential precursors to modern cells, could form under realistic early Earth conditions. Researchers pushed these conditions to the limits, ...

Researchers recreated conditions from billions of years ago and found that Earth’s young atmosphere could make key molecules linked to life. These sulfur-rich compounds, including certain amino acids, ...

How did life begin on Earth? While scientists have theories, they don’t yet fully understand the precise chemical steps that led to biology, or when the first primitive life forms appeared. But what ...

Early Earth got much of its water from relentless bombardment by water-rich asteroids and icy comets. Now, scientists say the young planet had a way to hold onto much more of that water than once ...

Continental clues: 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 ...
