HTTP:: Saturn Reveals New Temporary Radiation Belt
--------
Astronomers and physicists analyzing the data relayed back by the Magnetospheric Imaging instrument (MIMI) aboard the Cassini spacecraft have recently discovered a new, transient radiation belt around Saturn. Located some 337,000 kilometers away from the planet's core, the belt is located roughly around the moon Dione. Dr. Elias Roussos will present the discovery today, September 14th, at the European Planetary Science Congress, in Potsdam, Germany, AlphaGalileo reports. In addition to the Van Allen radiation belt that surrounds our planet, similar formations have also been identified around the largest planets in our solar system â€" Jupiter, Saturn, Uranus and Neptune. Thus far, experts have only managed to observe variabilities in radiation fields around our planet and on Jupiter, so the new study is the first to add Saturn to the list. The new find was only made possible by the fact that we have had Cassini in orbit around the gas giant for the past five years. Astro!
nomers explain that only a comparative, ongoing analysis can show variations such as the ones Cassini recorded. “The most dramatic changes have been observed as sudden increases in the intensity of high energy charged particles in the inner part of Saturn's magnetosphere, in the vicinity of the moons Dione and Tethys. These inten...
