Viewing Saturn’s northern polar region for a period of seven months, the NASA/ESA Hubble Space telescope snapped a series of stunning images of auroras dancing in the sky. The observations were taken before and after the Saturnian northern summer solstice.
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 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.
