Description:
This web-based lesson compares how auroral light produced on the Earth's atmospheric screen is similar to the images produced on the screen of a Cathode Ray Tube. It explains how viewing the aurora is like looking at a giant television screen in the sky and the colorful shimmering, shifting curtains of light of the Aurora Borealis (Northern Lights) and Aurora Australis (Southern Lights) are similar to the images produced on the screen of a television or computer monitor. The lesson covers particle creation and power production (what kinds and where particles are produced), directional control and movement of particles (what causes the particles to move), and particle interaction and ionization (with what the particles interact and how light is produced).
