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

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. Ultra Low Frequency Electromagnetic Waves at the Saturn Bow Shock

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

    Författare :Axel Lindberg; Johan Höglund; [2023]
    Nyckelord :;

    Sammanfattning : This project aims to research the characteristics and prevalence of ultra low frequency(ULF) waves at the Saturn bow shock with the help of data collected by the space probe CASSINIwhich was in orbit around the planet from 2004 and 2017. ULF waves have been extensively studiedat Earth but not at Saturn, and by studying this phenomenon at Saturn we may gain a deeperunderstanding of it. LÄS MER

  5. 4. Plasma density characteristics of magnetic holes near the Kronian magnetosphere boundary surfaces

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Marlon Luis Bause; [2020]
    Nyckelord :Magnetic holes; Saturn; Langmuir Probe; plasma electron density; Magnetosphere;

    Sammanfattning : Localized structures of the magnetic field strength depression are often observed in the interplanetarymedium, and they are called ‘magnetic holes’ after the original work of Turner et al. 1977. A numberof observations of similar features have been reported, while the mechanisms of their origin have notfully understood yet. LÄS MER

  7. 5. Capture of interstellar objects in the Solar system

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Jonathan Petersson; [2020]
    Nyckelord :interstellar objects; Physics and Astronomy;

    Sammanfattning : Research on InterStellar Objects (ISOs) has been done for several decades, however, the first observed ISO in the Solar system was only recently discovered in 2017. It was named 1I/'Oumuamua and was only passing though the Solar system, but this may not be the case for all objects of its kind. LÄS MER
