Introduction
Ever since the discovery of the Jovian dust streams by the Ulysses spacecraft dust detector in 1992, space scientists have wondered about the streams' origin. Before and since the Galileo spacecraft's arrival in the Jupiter system in December 1995, we recorded more dust stream measurements, this time with Galileo's dust detector instrument, which is a twin to Ulysses' dust instrument. Researchers narrowed the dust streams' origin to be in the Jovian system, with the possible sources being Jupiter's main ring, Jupiter's gossamer ring, comet Shoemaker-Levy 9, or Io. All but Jupiter's gossamer ring and Io have been ruled out. Here, from periodicities in the dust impact signal, we argue that the dominant source of the Jovian dust streams is Io.- Download the Whole Paper (PS) (PS text plus
