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 (icebreaker) a slightly smaller and cheaper (less than 500-million-euro) version, "Aurora Slim", has been suggested by the Finnish engineering company Aker Arctic. The most prominent change from "Aurora Borealis" to "Aurora Slim" is that the insulated drilling rig is no longer present. The scientist have to rely on a mobile system and shallower boreholes of a few hundred metres instead of more than . She will also have only a single moon pool instead of two as in the original concept. Like the original concept, the vessel is designed to break level ice up to in thickness. However, the dynamical positioning
