Aurora Aurora An aurora (plural: auroras or aurorae), sometimes referred to as polar lights, northern lights (aurora borealis) or southern lights (aurora australis), is a natural light display in the Earth's sky, predominantly seen in the high-latitude regions (around the Arctic and Antarctic). Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere (thermosphere/exosphere) due to Earth's magnetic field, where their energy is lost. The resulting ionization and excitation of atmospheric
Aurora Borealis (painting) Aurora Borealis (painting) Aurora Borealis is an 1865 painting by Frederic Edwin Church of the aurora borealis and the Arctic expedition of Isaac Israel Hayes. The painting measures and is now owned by the Smithsonian American Art Museum. "Aurora Borealis" is based on two separate sketches. The first incident was an aurora witnessed by Church's pupil, the Arctic explorer Isaac I. Hayes. Hayes provided a sketch and description of the aurora borealis display he witnessed one January evening. Coinciding with Hayes' furthest northern movement into what he named Cape Leiber, the aurora borealis appeared over the peak. Describing the event,
