You've probably wondered if life exists beyond Earth, a question that has puzzled humanity for centuries. Recent discoveries by NASA's Curiosity rover on Mars are bringing us closer to answering that, revealing surprising new clues about the Red Planet's past.
The Curiosity rover is trending because it just found new types of organic molecules on Mars, deep within ancient lakebed rocks.
This isn't the first time Curiosity found organics, but these new discoveries are more diverse and preserved, hinting at a richer chemical environment than previously understood.
