Earth Aurora Captured by NASA Astronaut Jonny Kim | International Space Station
Expedition 73 flight engineer and NASA astronaut Jonny Kim: "Caught a fish! Hope you enjoy this round of space fishing for beautiful auroras. If you’re wondering what the reflections in the lower left are, I made a rookie mistake of not having the shroud completely cover the window so you can see some crew activity (the cupola is located adjacent to one of our exercise devices)."
On Earth, auroras are mainly created by particles originally emitted by the Sun in the form of solar wind. When this stream of electrically charged particles gets close to our planet, it interacts with the magnetic field, which acts as a gigantic shield. While it protects Earth’s environment from solar wind particles, it can also trap a small fraction of them. Particles trapped within the magnetosphere—the region of space surrounding Earth in which charged particles are affected by its magnetic field—can be energized and then follow the magnetic field lines down to the magnetic poles. There, they interact with oxygen and nitrogen atoms in the upper layers of the atmosphere, creating the flickering, colorful lights visible in the polar regions here on Earth.
Earth auroras have different names depending on the pole where they occur. Aurora Borealis, or the northern lights, is the name given to auroras around the north pole and Aurora Australis, or the southern lights, is the name given for auroras around the south pole.
