Perseverance rover detects complex organics in ancient Martian river channel at Jezero Crater

NASA's Perseverance rover has detected complex organic compounds in Jezero Crater, a 45-km-wide formation on Mars that once held a freshwater lake billions of years ago fed by two river valleys. Researchers believe the river delta and lake formed under freshwater conditions, pointing to conditions potentially suitable for life. The discovery raises hopes of finding biosignatures on the Red Planet.
