Arctic bacteria can help find life on Europa

Bangalore Mirror Bureau [You must be registered and logged in to see this link.]

Canadian scientists have found a landscape similar to one of Jupiters icy moons: Europa located at Borup Fjord Pass in the Canadian High Arctic.It consists of a frozen and sulphurous environment,where sulphur associated with Arctic bacteria offer clues for the upcoming missions in the search for traces of life on Europa.
Here the sulphurous yellow emissions contrast with the whiteness of the environment,creating images similar to those captured at Jupiters satellite.
US researchers have now verified that the sulphur involved in the life cycle of Arctic microorganisms has some characteristics that could help to detect biological remains on Europa.Large space agencies like NASA and the European Space Agency are already in the process of preparing missions.We have discovered that elemental sulphur can contain morphological,mineralogical and organic biosignatures linked to bacterial activity.If they are found on Europa,this would suggest the possible presence of microorganisms, said Damhnait Gleeson,lead author of the study.The study appears in the Astrobiology journal.
