The aurora borealis, or Northern Lights, occurs when charged particles from the solar wind collide with Earth’s magnetosphere, exciting atmospheric gases that glow in green, violet, and crimson ribbons.
Prime viewing season runs from late September to early April within the auroral oval—regions like Tromsø, Norway; Yellowknife, Canada; and Fairbanks, Alaska offer dark skies and frequent displays.
Photographers recommend wide-angle lenses, sturdy tripods, and manual camera settings: ISO 1600–3200, aperture f/2.8, and 10–25-second exposures to capture the shifting curtains of light.
Beyond beauty, auroras reveal how solar activity affects satellite operations, power grids, and even migratory animals that navigate by magnetic fields.
Climate change may subtly shift auroral visibility, but enthusiasts continue chasing this celestial ballet, underscoring our planet’s dynamic connection to the Sun.
