Northern Lights Science

The Northern Lights, or Aurora Borealis, are a natural light display in the sky. They happen when tiny charged particles from the sun collide with gases like oxygen and nitrogen in Earth's atmosphere. These collisions release energy as beautiful, shimmering light that dances across the Arctic sky.

The sun constantly sends out a stream of charged particles called solar wind. When this wind reaches Earth, our planet's magnetic field channels the particles toward the polar regions, places like Finnish Lapland. That's why the auroras appear most often in a ring around the Arctic and Antarctic.

• Cloud cover can block the view, even when auroras are active above
• Solar activity changes daily, some nights are simply more active than others
• All conditions must align: clear skies, strong solar wind, and darkness

Camera sensors can absorb light over several seconds, capturing far more color and detail than the human eye sees in real time. That's why aurora photos often look more vivid and dramatic. In person, the lights may appear as soft, moving bands of pale green or white, still magical, just different from what you see on Instagram.
