How are northern lights formed?

It was the 14^th of January 2022, the night every person present in Stockholm actually in the whole of northern Europe would remember. Bright dazzling green light shining up in the sky, like the beautiful sparkle in the dark sky, yes it was auroras. It was among the strongest auroras witnessed. We could even see dancing red auroras in the sky. It is a rare phenomenon that occurs once or twice a year.

But how are the auroras formed?

They are the result of the disturbance of the earth's magnetic field. Well! To Make it interesting look at the image below:

When the sun gives out strong and hot solar flames(winds) they are so large that they reach earth and even move beyond it. These can cause severe harm to the people living on the earth, but there is a shield that protects us from these solar winds. This shield is nothing but our earth's magnetic field. This is what the earth's magnetic field looks like:

The hot solar flames traveling from the sun to the earth get blocked by the magnetic field. There are several gases in the sky, the solar waves and the gases form the electric field at the poles of the earth that gives out different colors. It's just that simple.

Where you can see the northern lights?

They are mostly observed at the north and south poles and in countries close to them. Norway, Finland, Sweden, Iceland, Canada, Russia, and Scotland. Unfortunately, northern lights are not visible from INDIA, as it is close to the equator.

At what season you can see these lights?

Starting at the end of the august month and till April is the good season to have a beautiful view of the auroras.

It is a short activity of about 30 minutes or 2 hours. Everyone must experience this unusual yet magical scientific activity of earth once in a lifetime!

It's always insane all those colors appearing in the space from just a chemical reaction. There are hundreds of secrets out there but we humans are still incapable of understanding them. We must dive deep into the new things and explore, and expand our vision above the daily chores.
