6. Optimization of Meteor Triangulations Using Timed Observations
Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : Meteors are light events appearing in the sky, looking like strips of light. A meteor occurs when a space object, a meteoroid, enters the earth’s atmosphere at high velocity and starts to glow. LÄS MER
7. Ett varv runt solen är väl en månad - eller är det tusen år? En jämförande intervjustudie om solsystemets himlakroppar med elever i årskurs 6.
Magister-uppsats, Göteborgs universitet/Institutionen för didaktik och pedagogisk professionSammanfattning : Syftet med denna studie är att undersöka hur flera- och multimodala representationsformer kan användas för att ta reda på hur elever förklarar himlakropparnas rörelser. Representationsformerna i denna studie består av skisser och en animerad 3D modell. LÄS MER
8. Search for Preserved Methanogenic Organisms in Ophiolitic Rocks through Lipid Biomarker Analysis – Implications for Astrobiological Explorations
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : 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.

9. Manned Mission to Mars: Water as Radiation Shielding During a Solar Particle Event
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : "Space agencies and privat e companies are working hard to solve the various challenges that need to be overcome to take humans to Mars . The journey to Mars has mult ifaceted risks for the crew, includin g radiation exposure. One risk factor that could jeopar dize t he crew's healt h is the radiation dose from a !arge solar partide event (SPE) .. LÄS MER
10. Effects of planetary radius contraction on scattering
Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : The observed high orbital eccentricities of many giant exoplanets is thought to be the result of gravitational scattering between planets. Outcomes of planet-planet scattering can result in some planets being lost by ejections into interstellar space, or collisions between planets or with the star. LÄS MER
