In an email interview with Newsweek, lead author Gaël Choblet, from the French National Center for Scientific Research, said that while he can not speculate on the presence of alien life on Enceladus, their timescale for hydrothermal activity does bolster the case that microbial life could emerge.

They range from hydrothermal activity, acid fog from extinct volcanos, and even efflorescence, which is how salt deposits form in basements or on brick walls.

Among the probe's major discoveries were Titan's liquid methane seas and a global ocean on Saturn's moon Enceladus that showed evidence of hydrothermal activity.
