1. Goal: To understand what makes Jupiter tick.
Objectives:
To learn about the Atmosphere
To explore its Formation
To explore its Core
To learn about Magnetic Field
To review the Shoemaker-Levy impacts

2. Does Jupiter have any rings?
Note to self, explain briefly formation here

3. Jupiter laid out
This is a composition of images from the Cassini spacecraft.
Notice the structure of the atmosphere.

4. Storms! Image from HST Jupiter has many storms in its atmosphere.
The most famous
is the giant red
spot.
How would Earth
compare to this
image?
What creates the
bands of Jupiter?

5. Bands of Jupiter:
Caused by convection of the atmosphere in the North-South direction as the atmosphere moves upwards.
This is also called “Hadley Circulation”.

6. Hadley circulation
As air moves North or
South, it moves E/W
because of the spin
of the earth.
Going up in
Latitude means
you have less
rotational Energy
(smaller radius).
Therefore, to
conserve energy,
the air moves
westward.

7. Applied to Jupiter:

8. Colors in Jupiter’s atmosphere:
The colors are due to different chemicals and temperatures for different parts of the atmosphere.
The red parts are clouds lower in the atmosphere which
are warmer and
absorb more sunlight.
The white parts are cooler clouds higher up in the atmosphere which reflect more sunlight.
(from Moons and Planets)

9. Jupiter in the Infrared
IR is opposite to the optical. Red parts in optical are bright yellow here and white parts are dark here.
How would the energy emitted in the IR compare to the energy absorbed from the sunlight?
A) same
B) much less
C) twice as much

10. Emit vs absorb: http://www.enterprisemission.com/hyper1.html

11. What is Jupiter mostly made of?

12. What is Jupiter mostly made of?
Helium~14%
Methane0.1%
Water vapor0.1%
Ammonia0.02%
Ethane0.0002%
Phosphine0.0001%
Hydrogen sulfide< %

13. Does Jupiter have a “solid” surface?

14. Jupiter’s core

15. Jupiter Magnetic Field

16. M field 2

17. Shoemaker Levy 9 comet In 1995 a comet crashed into Jupiter.
The comet a few years earlier had gone by Jupiter.
The tidal forces from Jupiter broke the comet into dozens of pieces.
From this we have learned a lot about asteroid impacts.

18. Fireball!
What does
this remind
you of?

19. aftermath

20. Conclusion Jupiter is a giant world with even greater weather.
Everything about Jupiter is big.
