Northern Lights

The Aurora Borealis (Northern Lights) is one of nature's most spectacular phenomena — a celestial light show produced when charged particles from the Sun interact with Earth's magnetic field and atmosphere. When solar wind reaches Earth, its charged particles are funneled toward the poles by Earth's magnetic field. As they collide with atmospheric gases at 100-300 kilometers altitude, they excite atoms that release energy as light — creating curtains, spirals, and waves of green, red, blue, and purple light. Green aurora comes from oxygen at 100km altitude; red from oxygen at higher altitudes; blue and purple from nitrogen. The patterns shift and dance in real time, creating an ever-changing celestial display. The best viewing locations are near the Arctic Circle: Norway, Iceland, Canada, Alaska, and Finland. Solar maximum periods intensify aurora activity, and they can occasionally be seen as far south as the UK or northern United States.
