NASA's Curiosity rover has found organic molecules on Mars that have never been detected before - hinting at the possibility there was once life on the Red Planet.

NASA's Curiosity rover has detected previously unseen organic molecules in a rock sample drilled on Mars in 2020, including a nitrogen heterocycle that serves as a chemical precursor to RNA and DNA. The discovery, confirmed after years of lab work, provides further evidence that ancient Mars had the right chemistry to support life, though scientists cannot determine whether the molecules originated from biologic or geologic processes.
