KONTAN.CO.ID – Get to know the aurora, how this phenomenon can occur. For those who are curious about this phenomenon, come on, find out more here.
What are auroras? And, how did this beautiful phenomenon come about?
Some people may still wonder how the aurora phenomenon occurs. The light that dances in the sky so beautifully is often found in the polar regions.
Including, around the North Pole and South Pole. Therefore, this aurora phenomenon is also often referred to as polar light.
What exactly is the aurora phenomenon?
Aurora is actually a natural phenomenon that produces glowing beams of light dancing in the night sky in the ionosphere layer of a planet.
This is a phenomenon that occurs due to the interaction between the magnetic field of a planet with charged particles emitted by the Sun called the solar wind.

Then, how did the aurora happen?
Quoting from NASA’s official page, spaceplace.nasa.gov, an aurora occurs when a solar storm comes toward Earth. Some of the energy and tiny particles can travel down the magnetic field lines at the North Pole and the South Pole into Earth’s atmosphere.
There, the particles interact with gases in Earth’s atmosphere to produce a beautiful light dancing across the sky. The green color that often appears in auroras comes from oxygen.
However, this oxygen also sometimes emits a red light. While nitrogen will produce blue and purple light on the aurora.
Speaking of aurora, on Earth there are two well-known aurora names. The first is the aurora Borealis. This phenomenon generally occurs in the sky at the North Pole.
The Aurora Borealis is seen with a reddish tint, generally occurring between March and April and September and October.

While the second aurora is named Australis. In contrast to Borealis, Astralis aurora occurs in the sky at the South Pole.
Aurora Australis tends to be rarely seen because it usually looks bright in sparsely populated areas. However, the aurora Australis is frequently seen in Australia on an 11-year cycle of sunspot activity.
Thus some information that you can understand regarding the aurora, the beautiful light that dances in the sky.
