A team has set out to the cold regions of the Arctic in order to discover the source of sulfur that has been appearing there for some time. They hope that these discoveries could help us locate life on a distant frozen world orbiting Jupiter.
(Astrobiology Magazine) “It’s out of the norm,” Pappalardo says. “Biology is expected to play a part in this. The fact that all [these forms of sulfur] were present in close proximity suggests that life is involved.”
While Pappalardo acknowledges that Europa’s outer surface contains too much radiation to ever support life, these findings could help answer the question as to whether life could exist below the surface of Europa.
I am not too sure how successful they will be, as Enceladus looks more promising, but a discovery of life on a foreign lunar body would help motivate humanity towards the stars.
