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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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. A quantitative analysis of plume gas distributions from different detection studies on Europa

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Anujan Ranganathan; [2023]
    Keywords : Europa; Water; Plume distribution; Surface Density; Column Density; Total number of molecules; Europa; Vatten; Plym Distribution; Ytdensitet; Kolumndensitet; Total mängd molekyler;

    Abstract : The search for water has been vital in our solar system as water indicates a potential for life. The search has been extended to satellites orbiting the outer planets. It has already been proven that water exists on Saturn’s moon, Enceladus, where the spacecraft Cassini did a flyby through a water plume. READ MORE

  4. 3. Search for Preserved Methanogenic Organisms in Ophiolitic Rocks through Lipid Biomarker Analysis – Implications for Astrobiological Explorations

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Alexandra Zetterlind; [2020]
    Keywords : ophiolite; deep biosphere; archaea; methanogenesis; chemosynthesis; serpentinite-hosted ecosystems; lipid biomarkers; astrobiology; ofiolit; djupbiosfär; arkeér; metanogener; kemosyntes; serpentinit-drivna ekosystem; lipidbiomarkörer; astrobiologi;

    Abstract : Serpentinization is a metamorphic low-temperature geological process, involving a series of chemical reactions that hydrate ultramafic rocks into serpentines and other minerals such as magnetite and brucite. Moreover, the process produces heavily reducing and highly alkaline fluids together with molecular hydrogen (H2) and methane (CH4), which have the capacity to support chemosynthetic microbial life.
