KOMPAS.com – Aurora is natural phenomenon in which colored light shines in the sky. However, does this phenomenon only occur on Earth?
Auroras are not unique to Earth. This phenomenon can also occur on other planets as long as the atmosphere is sufficiently dense. Auroras on other planets may actually be more spectacular than those on Earth.
James O’Donoghue, a scientist with the Japanese Aerospace Exploration Agency, provides an example aurora on another planet:

1. Mars
Although Mars has a weak magnetic field, aurora of Mars twice as surprising as the Earth’s aurora because the orbit of the red planet around the Sun is twice as far away as Venus.
Observations from the spacecraft show that although Mars has no magnetic field, there are still remnants of magnetic anomalies that react when collisions with charged solar particles occur.
The result of that interaction is a “subtle and winding” aurora, which surrounds half of the planet.
2. Saturn
In addition to Mars, aurora also occurs on Saturn due to weather conditions.

3. Uranus
Meanwhile, on Uranus, the aurora appears in complicated shapes and in unexpected places because the planet is tilted on its own axis.
4. Jupiter
However, among all the aurora researchers have known; The most powerful are the aurora on Jupiter.
A 2017 study in Nature found that Jupiter’s auroras are bursts of intense electromagnetic radiation that are 30 times more powerful than auroras on Earth.
It is so powerful that you will not be able to see the aurora on the giant planet with the naked eye because the light it emits is beyond what the human eye can perceive.
Another peculiarity of the aurora on Jupiter is that this phenomenon is not produced by solar storms as it happens on Earth.

According to NASAon that planet, auroras occur as a result of particles released into the magnetosphere by volcanoes on their moons.
