Astronomers have found possible chemical signs of life on a distant planet outside our solar system, though they caution more work is needed to confirm their findings. The research, led by scientists at the University of Cambridge, detected evidence of compounds in the exoplanet's atmosphere that on Earth are only produced by living organisms and contended it's the strongest potential signal yet of life. Independent scientists described the findings as interesting, but not nearly enough to show the existence of life on another planet.
