  1. 1. Antarctic Subglacial Lakes as Environmental Analogues for Possible Hidden Biospheres on the Moons Europa and Enceladus

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Jonas Fahlman; [2023]
    Nyckelord :astrobiology; icy moons; subglacial lakes; ice dynamics; thermal regimes; extremophiles; anthropogenic contamination; astrobiologi; ismånar; subglaciala sjöar; is-dynamik; termiska regimer; extremofiler; antropologisk kontaminering;

    Sammanfattning : The evolving science of astrobiology for the search for life beyond Earth has put focus on the possibility of subsurface bodies of liquid water beneath the surface of icy moons within our Solar System. Specifically, the Jovian moon of Europa and the Saturnian moon of Enceladus show telling characteristics of endogenous heating through their complex tidal resonances with their parent planets – suggesting the presence of oceans of liquid water and therefore a potential for astrobiology.

  3. 2. Methods and Approaches for Biogenicity Determination in Geological Samples - Implications for Extraterrestrial Search for Life

    M1-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Alexandra Zetterlind; [2018]
    Nyckelord :Biogenicity; microscopy; fossilized microorganisms; astrobiology; Biogenecitet; mikroskopering; fossiliserade mikroorganismer; astrobiologi;

    Sammanfattning : For a better understanding of how to search for an extraterrestrial life, scientists study hidden biospheres on Earth. The subseafloor crust is recognized as a vast microbial habitat and it is hypothesized that extremophilic microorganisms, occurring there, can be the first living organisms on Earth. LÄS MER

  4. 3. Analysis of metatranscriptomes from an acidophilic electricity generating community treating acidic mining wastewaters

    Master-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Författare :Daniela Palma; [2018]
    Nyckelord :Acidophiles; extremophiles; MFC; metatranscriptomic; bioinformatics; electricity production; AMD.;

    Sammanfattning : Human ́s constant need for metals requires unsustainable mining and refining of metalore. As a result, highly contaminated wastewaters are discharged in the environmentcompromising the nearby habitat together with all its life forms. LÄS MER

  5. 4. Martian Caves as Special Region Candidates : A simulation in ANSYS Fluent on how caves on Mars are, and what their conditions would be for being considered as special regions.

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Patrik Olsson; [2018]
    Nyckelord :mars; lava tubes; caves; special regions; relative humidity; temperature; perchloratic salts;

    Sammanfattning : One of the most interesting questions about Mars is if life ever existed on it. One of the main requirements for life to exist as we know it is the presence of liquid water. It has been suggested by Martín-Torres et al. LÄS MER
