Geysers on Mars: Difference between revisions

 

A multinational European team suggests that if liquid water is present in the spiders' channels during their annual defrost cycle, the structures might provide a niche where certain microscopic life forms could have retreated and adapted while sheltered from [[Ultraviolet|UV]] solar radiation.<ref name=Manrubia /> British and German teams also consider the possibility that [[organic matter]], [[microbe]]s, or even simple plants might co-exist with these inorganic formations, especially if the mechanism includes liquid water and a [[Geothermal gradient|geothermal]] energy source.<ref name=Ness /><ref>{{cite journal|title=Temporary liquid water in upper snow/ice sub-surfaces on Mars? |journal=Icarus|date=13 November 2009 |last1=Möhlmann |first=Diedrich T.F. |doi=10.1016/j.icarus.2009.11.013 |url=https://www.sciencedirect.com/science/article/pii/S0019103509004539|volume=207 |pages=140 |bibcode=2010Icar..207..140M}}</ref> However, they also remark that the majority of geological structures may be accounted for without invoking any organic "life on Mars" hypothesis.<ref name=Ness /> (See also: [[Life on Mars (planet)|Life on Mars]].)
