Mystery of Aurora

Auroras decorate the night sky in frigid regions, but how do they shine?
Why do they appear in frigid regions?
Come to think about it, you may have many questions about auroras.
The aurora phenomenon is not seen only on Earth, but also on Jupiter and Saturn.
Under what conditions do auroras occur?
In recent years, auroral studies have revealed that the Sun is the cause of auroras on Earth and other planets.
In addition to explaining how auroras are generated, based on the latest satellite and ground-based observational results, these lectures will also explain the perpetual solar surface fluctuation which is the source of auroral energy, and sunspot variation which particularly strongly influences the planetary environment.
