Cassini findings may indicate life on Titan
Cassini, the Saturn-orbiting module of the Cassini-Huygens joint mission, has recently sent back detailed spectrometric images of Titan’s atmosphere and surface.
Astrobiologists from across the world are arguing that the moon’s abundance of organic molecules indicates methane-based, hydrogen-breathing life or pre-life on Titan.
Many scientists are cautious, however, including Head Astrobiologist at NASA Mark Allen:
“Scientific conservatism suggests that a biological explanation should be the last choice after all non-biological explanations are addressed.”
