Aurora Borealis in Ersfjord, Norway. During the Northern Hemisphere's autumn and spring, solar magnetic fields are oriented in just the right way to cause "rips" in Earth's magnetic field. The resulting increase in solar wind on Earth encourages auroral sky shows but can also damage satellite technology and electrical grids on the ground. (National Geographic)

Now it was winter and a thin blanket of snow had carpeted the town, muting the oranges and reds and casting a magical shimmer along the banks.
