What is Aurora?

An Aurora is a display of light in the sky predominantly seen in the high latitude regions (Arctic and Antarctic). It is also known as a Polar light.

While usually a milky greenish color, auroras can also show red, blue, violet, pink, and white. These colors appear in a variety of continuously changing shapes.

Types of Aurora

1. Aurora Borealis
2. Aurora Australis

Why they occur?

Auroras are a spectacular sign that our planet is electrically connected to the Sun. These light shows are provoked by energy from the Sun and fuelled by electrically charged particles trapped in Earth’s magnetic field.

The typical aurora is caused by collisions between fast-moving electrons from space with the oxygen and nitrogen in Earth’s upper atmosphere.

Auroras affect communication lines, radio lines and power lines.

It should also be noted here that Sun’s energy, in the form of solar wind, is behind the whole process.
