15,000-year-old viruses discovered in Tibetan glacier ice
This is interesting, however for another reason is to ask the question could life therefore exist within ice on Exoplanets or Exomoons.
“These are viruses that would have thrived in extreme environments,” said Matthew Sullivan, co-author of the study, professor of microbiology at Ohio State and director of Ohio State’s Center of Microbiome Science
I think some of the moons around Saturn (e.,g Enceladus) have been identified as possible places where life could be. However these are also extreme environments.
However we also look at Habitable zones, so environments that we think would support life, in this case defined as “neither too hot nor too cold” is it worth defining or perhaps redefining what we mean by this.
