Auroras are beautiful light-show in the sky, which is caused by the sun. 

Auroras on the Earth are the result of disturbances in the magnetosphere (area of space, around the Earth, that is controlled by the Earth's magnetic field) caused by solar wind. It is a natural light display in the Earth's sky, predominantly seen in high-latitude/polar regions like the Arctic and Antarctic

Plasma from solar flares or coronal mass ejections travel along solar wind to ultimately produce aurora's in the Earth's polar regions. This visually stunning explanatory video takes you on a journey from sun's interior to the Earth's upper atmosphere.

How Auroras Are Formed ?

Visible only at night, an aurora is caused by the streams of electrified particles (which are emitted by the sun) trapped in the magnetic field of the earth. It is produced when this magnetosphere is disturbed by the solar wind carrying the charged particles.

Technically speaking, as solar wind approaches the Earth, it meets the Earth's magnetic field. In the ionosphere, the ions of the solar wind collide with atoms of oxygen and nitrogen from the Earth's atmosphere ( charging them). The energy released during these collisions causes a colorful glowing halo around the poles — Aurora.
