Claim: Pluto is in the universe.
Evidence: In September 2016 , astronomers announced that the reddish-brown cap of the north pole of Charon is composed of tholins , organic macromolecules that may be ingredients for the emergence of life , and produced from methane , nitrogen and other gases released from the atmosphere of Pluto and transferred about 19,000 km to the orbiting moon.
The panspermia hypothesis alternatively suggests that microscopic life was distributed to the early Earth by meteoroids , asteroids and other small Solar System bodies and that life may exist throughout the Universe.
