The northern lights occur when electrically charged particles from the sun — mostly electrons and protons — slam into earth's upper atmosphere at speeds of. But before diving into the details, let’s break it down into simple terms The northern lights are caused by the interaction between the magnetic fields of the sun and earth

Dr geoff vasil, who studies the sun’s workings at the university of edinburgh’s school of mathematics, explains how this creates an aurora.
The aurora's characteristic wavy patterns and 'curtains' of light are caused by the lines of force in the earth’s magnetic field
The lowest part of an aurora is typically around 80 miles above the earth's surface. The aurora borealis shines sporadically over the middle and high latitudes of the northern hemisphere, including voyageurs national park Your chance of seeing the northern lights is impacted by the type of radiation produced by the sun, your location on the earth, and whether night sky is both clear and dark Chances increase slightly during the winter because there are more hours of darkness.
When energetic particles from space collide with atoms and molecules in the atmosphere, they can cause the colorful glow that we call auroras The colors of an aurora come from atoms and molecules being energized by colliding with energetic particles in the upper atmosphere. Unlike other phenomena of the night sky, such as meteors and comets, the auroras are atmospheric phenomena, but what causes them Although auroras appear in the atmosphere, they are the result of extraterrestrial forces
However, these forces are not particularly alien.
The aurora borealis is formed when energetic particles from the sun, carried by solar wind, interact with earth’s magnetic field These particles are funneled toward the polar regions, where they collide with gases in earth’s atmosphere, producing colorful light displays. The colors in the aurora were once a source of mystery throughout human history But science says that different gases in earth’s atmosphere give off different colors when they are excited.
The northern lights science revolves around interactions between the solar wind and earth’s magnetic field
