So what is that mechanism? Scientists say that some of Saturn’s auroras are born from the winds that move inside the planet’s own atmosphere. This discovery has changed the understanding of planetary aurorae. It also solves a mystery about Saturn, why can’t we measure the length of the day on the planet?
NASA launched Cassini in 1997, which reached Saturn in 2004. Since then it has sought to measure how fast the planet rotates to determine the length of its day. Scientists were surprised to know that the rotation rate of Saturn has changed after the Voyager 2 spacecraft flew over this planet in 1981.
The scientists have published their findings in Geophysical Research Letters of the American Geophysical Union.
In the report of the University of Leicester, researcher Nahid Chaudhary has been quoted as saying that the actual rotation rate of a planet cannot change very quickly. Something unusual is happening on the planet Saturn. Scientists found that a significant proportion of Saturn’s aurorae stem from weather patterns in its atmosphere. This is responsible for the rate of rotation of this planet. This study explains how local atmospheric weather on a planet affects the formation of aurorae.
Saturn is the second largest planet in our solar system. It has always attracted the attention of scientists and amateur astronomers. It can be easily recognized by looking at the rings around Saturn. But its another feature is more than 60 moons of this planet. One of these moons has recently aroused the curiosity of scientists. According to another research, an ocean may be hidden under the frozen surface of Mimas, a small moon orbiting this planet.
