Maybe the sun is turbulent magicka, or magicka is leaking from the sun and somehow combusting...still wouldn't explain why vampires aren't weak to magicka, unless vampires are weak to heat, which explains Magnus burning them, and fire burning them, but then, the sun could be like a lid, and it's keeping mortals from entering Aetherius, so when mortals figure out space travel (srsly, Elder Scrolls, make it happen!) they don't go to Aetherius early.
