Explain how scientists might infer that a planet outside of our solar system might be capable of supporting life.

Planets outside solar system are referred to as exoplanets. some scientists have put forward suggestions that there could be living organisms residing in some of the exoplanets. scientists have suggested that some exoplanets are found within the habitable distance from the star they revolve around. at this distance temperature can allow existence of liquid water. Where there is water automatically there is life. so astronomers may infer that life exist in exoplanets by determining whether they are with habitable distance from their star.
