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) of the north, "The Icebergs" (1861), the intact ship highlights Hayes' achievement in navigating this space, as well as the state of the nation in navigating the contentious historical moment. Presenting the ship's safe passage through the dark Arctic environment, Church suggested optimism for the future; a tiny light shines out from the ship's window. Charles Millard describes Church's paintings as "large in scale and size, sharply horizontal in format" and "dramatic in subject, but yielding in execution, and tend[ing] to exploit both value contrast and continuous tonal transition." Church's works, including "Aurora Borealis," were completed using small touches of
