'''''(background information):''''' |
'''''(background information):''''' Earth microbes live in the slow lane at lower temperatures to the point where individual microbes have lifetimes of millennia. Such life is hard to study. It's almost impossible to tell whether it is |

# active and able to reproduce at those temperatures |

# active and not able to reproduce, or |
|||
# intermittently sometimes active and sometimes dormant. |

Reproduction of such slowly growing cells can't be studied using cell counts. But the usual limit cited is -20 °C<!-- see discussion in A new analysis of Mars "Special Regions" -->. That's well above the lowest temperatures studied in the paper which go down to -133 °C. |
