Presentation Transcript

  1. Chapter 5: Moons of Jupiter Triton, a moon of Neptune

  2. Moons of the solar system: 3 categories: 7 large (each is distinctive) 12 medium-size many small (most are captured)

  3. Jupiter, Up Close, showing two moons in transit

  4. Jupiter, Callisto, and Europa

  5. Jupiter and Io

  6. Jupiter and Ganymede

  7. Galilean Moons of Jupiter, shown in relative size

  8. Galilean Moons of Jupiter, relative size, quarter phase, b/w

  9. Galilean Moon Orbits

  10. Galilean Moon interiors are quite distinct from each other

  11. Io, the most volcanic object in the solar system, due to tidal forces between Io, Europa, and Jupiter

  12. Io Notice the large ring of volcanic ejecta around a volcano

  13. Io

  14. Io A volcanic plume is seen on the left limb. The plume is about 150 km high.

  15. Io A volcanic plume is seen on top . The hot spot below that is the volcano.

  16. Io A volcanic eruption is seen in a caldera.

  17. The New Horizons spacecraft flew by in 2007 and saw some changes in the volcanic activity on Io.

  18. A detailed map of Io taken by the New Horizons spacecraft (June 2007) shows some changes in the volcanic activity on Io.

  19. Pictures of Io taken by the New Horizons spacecraft in Feb-Mar 2007 show moving material in the plume of the Tvashtar volcano on Io. The plume is roughly 330 kilometers (200 miles) high. A hot spot (the volcano) is seen in the night side at bottom right.

  20. Europa

  21. Europa, with an enhanced image on the right

  22. Europa terrain compared to terrain on the Earth at a similar scale

  23. Ganymede

  24. Ganymede has an icy surface with cracks similar to those seen on Europa and other moons.

  25. Ganymede terrain and a “flyover” animation generated by computer

  26. Ganymede has a string of craters that are probably due to a comet that broke up at it passed Jupiter, then impacted on Ganymede.

  27. Callisto

  28. More detail of the surface of Callisto

  29. Jupiter’s Red Spot compared to the sizes of the four Galilean moons (in a photomontage)
