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

Again this green overrides the red; blue and orange clasp each other in their rapid flight; violet darts tear through a broad flush of yellow, and countless tongues of white flame, formed of these uniting streams, rush aloft and lick the skies. The iconography of the painting suggested personal and nationalistic references. The peak in the painting had been named after Church during Hayes's expedition. "Aurora Borealis" incorporated details of Hayes' ship, drawn from a sketch he brought back upon returning from his expedition. Contrasted with Church's earlier painting
