Aurora Borealis, or the "northern lights", occurs 80 to 160 km (50 to 100 miles) above the earth when energetic particles from a solar storm cause the gases in the upper atmosphere to glow. Auroras can last between a few minutes to several hours. It's common across Alaska and northern Canada.

One of Jupiter’s moons, Io, has powerful volcanic activity that spews particles into Jupiter’s magnetosphere. These particles create intense radiation belts and auroras around Jupiter.

On calm, clear days, stars and auroras cast green and white light downwards with such intensity that I can occasionally see my shadow and the forms and curves of the ice cap — everything bathed in ghostly colors, the auras of a cold, harsh and indifferent world.
