>>7617110>Life on exoplanetsIt's possible, but the planets are too far away for it to matter in the next 1000 years.
>Life in our solar systemI think the best opportunity to find life is on Europe, but there are other good candidates. If not, we have to reevaluate how likely we think life occuring through abiogenesis is. By which I mean, clearly life occured at least once through abiogenesis, but the likely hood may be so small that it only occurred once in our solar system, even given other bodies with active cores for energy, liquid water, organic molecules, etc. Though I don't believe we know Europa's Iron content. Last year there was a paper on archea metabolism which put for that ferrous molecules were a big part of early metabolic systems arising, so ferrous molecules may be a sort of necessary stepping stone.
