Anddeclared The American Space and Aeronautics Agency (NASA) has already reported this image, and it is in a statement – the image was taken by the “Juno” spacecraft on December 30, 2020, when it was at an altitude of about 30,000 km. Jupiter’s atmosphere.

Ammonia-rich clouds

The image was taken of a region near the planet’s north pole, where a large vortex of stormy winds and dense clouds appears, and the scientists managing the mission noticed a green glow on one side of the vortex. , scientists discovered that the glow was created by the planet’s lightning.

On Earth, lightning originates from water-layered clouds, but on Jupiter, lightning bolts occur in clouds containing large amounts of ammonia water solution or ammonium hydroxide, so the glow from these lightning strikes is often seen in green near the poles.

In 2010, the Cassini spacecraft was also able to observe lightning on Saturn (NASA).

Not exclusive

It is worth noting that lightning also occurs on other planets and is not limited to Earth’s atmosphere. The first observation of lightning was recorded On Jupiter’s surface in 1979, when NASA’s Voyager 1 spacecraft flew across Jupiter, it detected bright lights in the night sky of the planet.

In addition, these flashes were accompanied by low-frequency radio signals, which unequivocally indicated the presence of lightning.
