===Dust storms===
In August 1995, the ''Galileo'' orbiter encountered a severe dust storm {{convert|63|e6km|e6mi|sp=us}} from Jupiter that took several months to traverse. Normally the spacecraft's dust detector picked up a dust particle every three days; now it detected up to 20,000 particles a day. Interplanetary dust storms had previously been encountered by the ''[[Ulysses (spacecraft)|Ulysses]]'' probe, which had passed by Jupiter three years before on its mission to study the Sun's polar regions, but those encountered by ''Galileo'' were more intense. The dust particles were 5 to 10&nbsp;nm in size, about the same as those in cigarette smoke, and had speeds ranging from {{convert|90,000|to|450,000|mi/h|km/h|order=flip|sp=us}} depending on their size. The existence of the dust storms had come as a complete surprise to scientists when ''Ulysses'' encountered them. While data from both ''Ulysses'' and ''Galileo'' hinted that they originated somewhere in the Jovian system, it was a mystery how they had been created and how they had escaped from Jupiter's strong [[gravitational field|gravitational]] and [[electromagnetic field]]s.<ref>{{cite press release |title=Galileo Flying Through Intense Dust Storm |publisher=NASA/Jet Propulsion Laboratory |first1=Douglas |last1=Isbel |first2=James H. |last2=Wilson |id=95-147 |url=https://www.jpl.nasa.gov/news/galileo-flying-through-intense-dust-storm-on-way-to-jupiter |access-date=15 April 2024}}</ref>{{sfn|Meltzer|2007|pp=195–196}}{{sfn|Graps|Grün|Svedhem|Krüger|2000|p=49}}
