What you will learn
The Sun on a beautiful day is peaceful and nurturing. But if you step outside the protection of the Earth's atmosphere the sun becomes a deadly furnace of ignited nuclear fuel. Discover how the Sun affects the Earth with aurora and magnetic storms and take a close up look at the furnace of the Sun where you will find solar tornadoes the size of North America and temperatures of more than 25 million degrees. Lost in the flames of the Sun is the planet Mercury, stripped of everything by the violence of the Sun but none the less speeding around it every 88 days.
