With Discovery’s tail is in the foreground, the aurora australis, or southern lights, blaze over Earth’s horizon in this photo from the STS-85 mission in 1997.
Auroras occur near the north and south poles when charged particles from the sun interact with Earth’s magnetic field.
Also An aurora is a natural light display in the Earth’s sky, predominantly seen in the high-latitude region. Therefore Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind. The trajectories of charged particles in both solar wind and magnetospheric plasma. And 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.
