JEDI (Jovian Energetic Particle Detector Instrument), is an instrument on the Juno spacecraft sent to orbit planet Jupiter. It is part of a suite of instruments to study the magnetosphere of Jupiter.

The Jedi are the main protagonists in the fictional Star Wars universe. They are an ancient monastic, spiritual, and academic meritocratic organization whose origins dates back to circa 25,000 BBY (Before Battle of Yavin; the destruction of the first Death Star). The Jedi Order mostly consists of polymaths: teachers, philosophers, scientists, physicians, diplomats and warriors, who value knowledge and wisdom above nationality. By serving others, the Jedi give of themselves through acts of charity, citizenship, volunteerism, and good deeds. Their traditional weapon is the lightsaber, a device which generates a blade-like controlled plasma flow. The organization has inspired a new religious movement, Jediism.
