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
Corona Borealis of the Tuamotus named it "Na Kaua-ki-tokerau" and probably "Te Hetu". The constellation was likely called "Kaua-mea" in Hawaii, "Rangawhenua" in New Zealand, and "Te Wale-o-Awitu" in the Cook Islands atoll of Pukapuka. Its name in Tonga was uncertain; it was either called "Ao-o-Uvea" or "Kau-kupenga". In Australian Aboriginal astronomy, the constellation is called "womera" ("the boomerang") due to the shape of the stars. The Wailwun people of northwestern New South Wales saw Corona Borealis as "mullion wollai" "eagle's nest", with Altair and Vega—each called "mullion"—the pair of eagles accompanying it. The Wardaman people of northern Australia held the constellation
