Prerequisites

What you need to understand first.

  • Air L3 (requires) polysemous
    Auroras are light phenomena in the atmosphere
  • Magnetosphere L3 (requires)
    The magnetosphere traps and directs charged solar particles, creating the conditions for auroras.
  • Light L6 (requires)
    Understanding light is essential for grasping aurora
  • Solar Wind L8 (requires)
    The solar wind provides the charged particles that, when scattered, produce auroral displays.
