Mysterious Light show – Aurora

the light show we see is caused by electrically charged particles from space entering the Earth’s upper atmosphere at a very high speed. These electrically charged particles constantly pushing out from the sun (called solar wind), and they travel at between 300 and 500 km per second in all directions. As we revolve around the sun, a small fraction of those charged particles from the solar wind are catch by the earth. Around 98% of these particles are deflected by the Earth’s magnetic field.
