Summary

The aurorae are formed when solar wind particles, primarily protons and electrons, collide with Earth's atmosphere, causing atoms to become ionized or excited, and releasing energy as visible light. The solar wind is made up of charged particles and has variable properties, with a density of around 5 protons per cubic centimeter at Earth's distance from the Sun. The particles are trapped by Earth's magnetic field and directed towards the magnetic poles, forming the Van Allen belt, which enters the atmosphere at the poles and causes the aurorae. The aurorae can be simulated in a classroom using a terrella, a small magnetized sphere, and a vacuum chamber, to demonstrate the interaction between the solar wind and Earth's atmosphere.
