"Flying through the aurora at 28,000 kph"

07.04.10

This image is simply fantastic. The aurora, commonly called the northern lights, are caused by subatomic particles slamming into our atmosphere and ionizing the oxygen and nitrogen atoms there like shrapnel from bullets hitting a target. Guided by the Earth’s magnetic field, these particles tend to hit at high latitudes. The glow itself is similar to that of a neon sign: when the wayward electrons recombine with the atoms, they give off light. The colors are characteristic of the atom in question, and can be used to identify the atmospheric constituents
