Researchers have analysed the oxygen isotope ratios in fossilised dinosaur teeth, specifically the tooth enamel. The tooth has preserved traces of the ancient atmosphere. The researchers studied these ...

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 ...

Early Mars may have been a warm version of modern Titan and at least as promising a site for the origin of life as early Earth was, if not more promising. The data constraining the model is the ...

Scientists in the New York Center for Astrobiology at Rensselaer Polytechnic Institute have used the oldest minerals on Earth to reconstruct the atmospheric conditions present on Earth very soon after ...
