  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. Conceptualisation, Implementation and Commissioning of a Controlled Pyrolysis Rig : KTH Master Thesis Report

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Arjun Monga; [2023]
    Keywords : coke deposition; pyrolysis; catalysis; methane; sample; cooling channels; regenerative cooling; rocket engines; koksavsättning; pyrolys; katalys; metan; prov; kylkanaler; regenerativ kylning; raketmotorer;

    Abstract : Liquid methane has seen popular interest from industry and academia as a next-generation rocket fuel due to its favorable performance characteristics and potential for extra-terrestrial in-situ resource utilisation. Since the rocket combustion chamber and nozzle are subject to high heat loads, regenerative cooling is a standard method to achieve lower temperatures. READ MORE

  4. 3. 'Oumuamua : An analysis of the the debate regarding the first interstellar visitor

    University essay from Uppsala universitet/Teoretisk astrofysik

    Author : Erik Westergren; [2022]
    Keywords : Oumuamua; asteroid; comet; Avi; Loeb; extraterrestrial; Pan-STARRS; interstellar; alien; vessel; Oumuamua; asteroid; komet; Avi; Loeb; utomjordiskt; PAN-STARRS; interstellär; farkost;

    Abstract : In the year of 2017 in October a strange object with a hyperbolic trajectory was observed in our solar system. There were several hypotheses that scientists used to try to explain what kind of an object it was, but no one could, according to the scientific community as a whole, perpetuate any of these explanations as accepted consensus.

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

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Markus Strickert; [2020]
    Keywords : Physics and Astronomy;

    Abstract : 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. READ MORE

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

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

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

    Abstract : 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. READ MORE
