Accidentally exposed yellowish-green crystals reveal ‘mind-blowing' finding on Mars, scientists say

The Curiosity rover has discovered rocks made of pure sulfur on Mars. During its exploration, the rover drove over a rock and cracked it open, revealing yellowish-green crystals that had never been seen before on the red planet. This finding is considered the strangest and most unexpected of the entire mission. The rock was found in the Gediz Vallis channel, which was created billions of years ago by a mix of water and debris. Scientists are now working to understand the significance of the presence of pure sulfur on Mars and its implications for the planet’s history.
