  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.

    Sammanfattning : Derek Parfit är kanske en av vår tids mest kända moralfilosofer. Parfit inleder sin första bok Reasons and Persons med att ställa frågan: vad har vi mest skäl att göra? Hans fråga berör vad som egentligen har betydelse, en fråga som han fortsätter att beröra i sin andra bok On What Matters. LÄS MER

  4. 3. Galactic Dynamics and the spread of Galactic Civilisations

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Markus Strickert; [2020]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Abstract The idea of the spread of life through the galaxy is, in most minds, considered science fiction. Yet, scientists argue that most galaxies have had more than enough time for civilisation development and space travel. LÄS MER

  5. 4. Europa's Lyman-Alpha Shadow on Jupiter

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Johan Ferm; [2020]
    Nyckelord :Europa moon ; Jupiter; water; plumes; Solar System; planets; satellites; hydrogen; Lyman-alpha; Europa måne ; Jupiter; vatten; plymer; solsystemet; skugga; planeter; satelliter; väte; Lyman-alpha;

    Sammanfattning : Europa is one of the most interesting satellites in the solar system in the search ofextra-terrestrial life, as it harbours an interior water ocean under its icy surface. Watervapour in Europa’s atmosphere has been previously observed, suggesting water plumeeruptions from the surface. LÄS MER

  7. 5. 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
