Rubies Found on Mars? Scientists Reveal | Cedar Rapids News

Scientists may have spotted rubies on Mars—well, the mineral that makes them, corundum—thanks to NASA’s Perseverance rover and its SuperCam laser. Found in Jezero Crater, this rare aluminum oxide could turn red with iron or chromium impurities, forming rubies—or blue as sapphires. While not enough for mining, it’s the first confirmed corundum on Mars, offering clues about Earth’s ancient past since we’ve lost most of our 4-billion-year-old rocks. Future missions may bring samples back for closer analysis, turning a distant laser into a cosmic gem hunter. Listen in comfort:Get a discount on a Soli Pillow: http://solipillow.com/discount/dnn.
