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) system of the smaller vessel consists of three 15MW azimuth thrusters and two 3.5MW bow thrusters instead of three fixed propeller shafts with 27MW propulsion motors and six 4.5MW rectractable transverse thrusters. The number and output of generating sets has also been reduced. The participants in the "Aurora Borealis" project are listed in the following table. Aurora Borealis (icebreaker) Aurora Borealis is a proposed European research icebreaker, comparable to the world's strongest icebreakers, planned jointly by a consortium of fifteen participant organizations and companies from ten European nations. If built, she would be the largest icebreaker ever built as well
