In 1952, Stanley Miller and Harold Urey made sparks fly in a gas-filled flask meant to reflect the composition of Earth's atmosphere around 3.8 billion years ago. Their results suggested that ...

Research partly conducted at the Advanced Photon Source helped scientists discover the composition of Earth's first atmosphere. What they found raises questions about the origin of life on Earth. A ...

There aren’t a lot of individual experiments that have ended up being staples of high school textbooks, but Stanley Miller and Harold Urey did one of them. Miller and Urey are the people who sealed up ...

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, ...

Using primitive meteorites called chondrites as their models, earth and planetary scientists at Washington University in St. Louis have performed outgassing calculations and shown that the early Earth ...

A new University of Colorado at Boulder study indicates Earth in its infancy probably had substantial quantities of hydrogen in its atmosphere, a surprising finding that may alter the way many ...

Collisions among molecules in early Earth’s atmosphere may have prevented our planet from freezing over eons ago, when the sun was much dimmer than it is today, keeping the world warm enough for life ...
