An aurora is a natural light display predominantly seen in the polar regions, caused by the interaction between the Earth’s magnetic field and charged particles from the Sun. These particles are carried towards the Earth by the solar wind and are mostly electrons and protons. When these charged particles collide with gases in the Earth’s atmosphere, they excite the atoms, causing them to light up. The auroras occurring around the north pole are known as Aurora Borealis or Northern Lights, while those around the south pole are called Aurora Australis or Southern Lights. These displays can vary in color and complexity, from faint glows to rapidly shifting ribbons of light, depending on the type of gas particles involved and their altitude. This celestial phenomenon is not only a beautiful natural spectacle but also part of the larger space weather system that can affect satellite operations and power grids on Earth.
