Researchers have found that early Earth’s atmosphere could naturally produce sulfur-based biomolecules, including amino acids like cysteine. Using light and simple gases, they recreated conditions that created complex molecules long thought to require living organisms. These findings suggest that li...

Electrical sparks inside Martian dust devils have been detected for the first time, reshaping how scientists understand the planet’s atmosphere and climate. On Mars, strong winds routinely generate swirling columns of fine dust. While passing through the center of two such dust devils, the SuperCam ...

Webb just revealed Uranus’s upper atmosphere in 3D, exposing wild auroras and a planet that is still cooling.
