Jupiter flyby February 8, 1992. • Galileo Orbiter/Atmospheric Probe - 1995 – 2003. • Hubble Space Telescope - observations since April 25, 1990. • Cassini – en route to Saturn, December 2000, and now there.
  4. 4. Voyager Spacecraft
  5. 5. Galileo Mission toJupiter and its moons
  6. 6. The VoyagerSpacecraft on its way,looking backat Earth and our Moon
  7. 7. Galileo atmospheric probe of Jupiter’s atmosphere - December 7th, 1995 Depth of measurements ~200 km
  8. 8. Jupiter, with its dark belts (where gases move down into the interior), and light zones(where gases move upwards). Alsovisible is the Great Red Spot, a huge hurricane that hasbeen observed from Earth for ~ 350 years, and other more or lesstemporary surface features

  11. 11. Some features in Jupiter’s dynamic atmosphere change just like weather on Earth. The 2 images are 10 hours apart.
  12. 12. Winds at top of atmosphere – travel in opposite directions at different latitudes
  13. 13. Observed circulation of Jupiter’s Red Spot
  14. 14. Jupiter’s Red Spot is a 350 year old hurrican! Nighttime image showing lightning in Jupiter’s atmosphere
  15. 15. Other storms (“small spots”) in Jupiter’s atmosphere
  16. 16. Ring around Jupiter,discovered by the Voyager Spacecraft
  17. 17. Ring system – made of fragments of ice 182,000 kmMoons insidering system
  18. 18. Internalstructureof Jupiter
  19. 19. Strength of the magnetic fields of the planets.Jupiter has by far the strongest magnetic field, because its interior is made of an excellent electric conductor (liquid metallic hydrogen), and because the planet rotates around its axis faster than any other (once in 10 hours).
  20. 20. Aurora at poles of Jupiter – show that Jupiter has a strong magnetic field
