Of all the planets in our solar system, Saturn has always attracted the attention of scientists for its unique appearance and vast size. Now, recent research has uncovered a method that has never been seen before, fueling the giant planets Aurora on Saturn. The study, published in Geophysical Research Letters, found out how Saturn is unique among the solar system’s planets because some of its auroras are produced not only by the magnetic field around the planet but also by the winds moving in its own atmosphere. Researchers explain that of all the other observed planets, including Earth, the aurora is formed only by the powerful currents that flow into the planet’s atmosphere from the surrounding magnets. These powerful currents are driven either by interactions with the Sun’s charged particles or by volcanic eruptions from the Moon orbiting the planets in Jupiter and Saturn.
The study was conducted by NASA’s Jet Propulsion Laboratory (JPL), Japan Aerospace Exploration Agency (JAXA), and colleagues from the University of Wisconsin-Madison, Boston and Lancaster, Imperial, University of Leicester and astronomers. And University Colleges, London, to address the decades-old question.
