The Northern Lights

Solar wind paints the sky by exciting gases high above us

Green curtains ripple across a night sky with nothing burning and no lamp anywhere. So what is glowing up there?

You'll find out

  • Where the glowing particles come from
  • Why the lights come in different colors
  • Why a phone camera sees them better

Why it matters

The storms that paint the sky can also knock out power and radio. Knowing how they work helps you catch the show.
