Earth Aurora | International Space Station
Expedition 73 flight engineer and NASA astronaut Anne McClain: "Auroras from space always draw crewmembers to the Cupola. I love how this one illuminated our Dragon, and I also love the dance of satellites on the left in the latter part of the video. It’s interesting how the aurora creeps along the top of the atmosphere as it comes up over the horizon. I have added traveling to see auroras from Earth to my bucket list!"
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.
