🌌 Guide to Aurora Colors
Every shade in the northern lights reveals a secret of the sky:
♥️ Red — Created by high-altitude oxygen, glowing faintly above 150 miles. Rare and hauntingly beautiful.
💚 Green — The classic aurora color, formed by oxygen lower in the atmosphere — bright, vivid, and most often seen.
💜 Purple / Blue — Produced by nitrogen close to Earth’s surface, shining during the strongest geomagnetic storms.
Each light is a pulse of solar energy meeting Earth’s magnetic heart — nature’s most magical connection between Sun and sky.
