In the northern latitude, the effect is known as aurora borealis ( aurora: the goddess dawn, borealis: north wind). While in the Antarctic region, the effect is known as aurora australis. They illuminate the northern and southern horizon as greenish glow or sometimes faint red, occasionally blue but most often in fluorescent green. Auroras can be seen at night because their light is not as strong as the light of the day. The aurora phenomenon occurs when the sun produces solar wind. Solar wind is a stream of electrons and protons which are released from the sun due to the high kinetic energy. These particles are charged and contain en
