Auroras, those effects of light in the upper layers of the atmosphere due to charged ions and moving by magnetism of the planet. The effect of the solar wind on the magnetosphere of a planet (in a nutshell).
All planets with strong magnetic field (either by its core, its size or its composition) have auroras. Visually checked on Mars, Saturn and Jupiter (no pictures).
Being on the ISS (International Space Station on) is experience first hand and from the top of this wonderful ballet of nature. As the image.
