| Oct 25, 2014 at 19:03 | comment | added | Tim B | @celtschk Yep, it's an issue of the energy available to your metabolism, to perform chemical reactions, etc. Colder temperatures generally reduces all those sort of things whether frozen solid or not. If it's enough to stop life being possible I honestly don't know. | |
| Oct 25, 2014 at 15:39 | comment | added | David Richerby | I dunno what it'd look like but it'd smell pretty bad! :-) (OK, not to anything that lived there, since they'd obviously not evolve to be able to smell ammonia, in the same way that we can't smell nitrogen or oxygen.) | |
| Oct 25, 2014 at 12:25 | comment | added | celtschk | @TimB: Of course water-based life has problems at temperatures much below freezing point, exactly because water freezes below freezing point (dissolved substances reduce the freezing point, but not arbitrarily much). I'd expect ammonia-based life to only have problems below ammonia freezing point. However, the lower temperatures might mean that all life processes are much slower. | |
| Oct 25, 2014 at 12:20 | comment | added | celtschk | @Superbest: I'd assume the life forms to be carbon based. Basically, nitrogen would replace oxygen, not carbon. | |
| Oct 25, 2014 at 6:37 | comment | added | Superbest | @TimB (and also OP) Are these supposed actual nitrogen based lifeforms, or just carbon backbone with nitrogen incorporated (which is what we have on Earth)? I think nitrogen based life is difficult because nitrogen can only make 3 bonds (vs. carbon and silicon making 4). I suppose you could have life just like on Earth, except adapted for cold and the very alkaline ammonia. | |

| Oct 24, 2014 at 22:43 | comment | added | Tim B | Your main problem is going to be the energy to maintain life. If it gets too cold on earth then life just stops running. Could an ammonia-based organism survive and metabolize in the ammonia temperatures? We just don't know... | |
