An international team of scientists has published a study highlighting the potential role of iron sulfides in the formation of life in early Earth’s terrestrial hot springs. According to the researchers, the sulfides may have catalyzed the reduction of gaseous carbon dioxide into prebiotic organic molecules via nonenzymatic pathways.

This work, appearing in Nature Communications, offers new insights into Earth’s early carbon cycles and prebiotic chemical reactions, underscoring the significance of iron sulfides in supporting the terrestrial hot springs origin of life hypothesis.

The study was conducted by Dr...

The asteroid that causes the Geminid shooting star swarm has also puzzled researchers with its comet-like tail. The infrared spectrum of rare meteorites helped to determine the composition of the asteroid.

Asteroid Phaethon, which is five kilometers in diameter, has been puzzling researchers for a long time. A comet-like tail is visible for a few days when the asteroid passes closest to the Sun during its orbit.

However, the tails of comets are usually formed by vaporizing ice and carbon dioxide, which cannot explain ...
