- *Jupiter's Outer Moons
Jupiter's eight outer moons fall into two groups: Leda, Himalia, Lysithea and Elara at about 11 million km from Jupiter and Ananke, Carme, Pasiphae and Sinope at about 23 million km. http://seds.lpl.arizona.edu/nineplanets/nineplanets/jupouter.html (Added: Mon Oct 28 2002)

- Galileo Spacecraft
Galileo is a NASA spacecraft mission to Jupiter, launched October 18, 1989, and designed to study the planet's atmosphere, satellites and surrounding magnetosphere for 2 years starting in December 1995. It was named for the Italian Renaissance scientist who discovered Jupiter's major moons in 1610 with the first astronomical telescope.

- Great Red Spot
The Great Red Spot is a great anti-cyclonic (high pressure) storm akin to a hurricane on Earth, but it is enormous (three Earths would fit within its boundaries) and it has persisted for at least the 400 years that humans have observed it through telescopes. http://csep10.phys.utk.edu/astr161/lect/jupiter/redspot.html (Added: Mon Oct 28 2002)
- Great Red Spot
These images were collected by Amy Simon (Cornell U.), Reta Beebe (NMSU), Heidi Hammel (Space Science Institute/MIT), their collaborators, and the Hubble Heritage team (AURA/STScI/NASA).

- Jupiter - The Nine Planets
The Nine Planets is an overview of the history, mythology, and current scientific knowledge of each of the planets and moons in our solar system. Each page has text and images, some have sounds and movies, most provide references to additional related information.

- Jupiter Events
This page contains information about how to find Jupiter in the night sky and how to find the Great Red Spot and the Galilean Satellites. It also has information about the 1994 collision of comet Shoemaker-Levy 9 with Jupiter. http://www.physics.sfasu.edu/astro/jupiter.html (Added: Sun Oct 06 2002)
- Jupiter Fact Sheet
Contains the mass, volume, escape velocity, orbital elements, spin rate, information about the moons of Jupiter, and many other parameters. http://nssdc.gsfc.nasa.gov/planetary/factsheet/jupiterfact.html (Added: Sun Oct 06 2002)
- Jupiter Observing Tool
This site shows you the relative positions of Jupiter's four largest moons. http://astronomy.physics.tamu.edu/galileo.html (Added: Sun Oct 27 2002)
- Jupiter's Rings
The images on the page shows that Jupiter also has a ring, though it is extremely faint. The ring was discovered by Voyager I in 1979 and is at a radius of about 1.8 times the radius of the planet (which is inside the radius of the innermost moon). It seems to be composed of small (micron size) particles, probably from Io's volcanoes and from debris knocked off the inner moons by meteor impacts.

- The Collision of Comet Shoemaker-Levy-9 with Jupiter
The shattered comet Shoemaker-Levy 9 collided with Jupiter over a 5.6 day period in July 1994. The first of 21 comet fragments hit Jupiter on July 16, 1994 and the last on July 22, 1994. This page offers answers to frequently asked questions. http://www.physics.sfasu.edu/astro/sl9.html (Added: Sat Oct 26 2002)
- The Interior of Jupiter
Most of the interior of Jupiter is liquid (primarily hydrogen and about 10% helium). The central temperatures are thought to lie in the 13,000-35,000 degree Celsius range, and the central pressure is about 100 million Earth atmospheres. We infer indirectly that the small core (perhaps a few tens of Earth masses) is rocky.

- The Magnetic Field of Jupiter
Jupiter has a large, complex, and intense magnetic field that is thought to arise from electrical currents in the rapidly spinning metallic hydrogen interior. http://csep10.phys.utk.edu/astr161/lect/jupiter/magnetic.html (Added: Sat Oct 26 2002)
- Voyager Mission to Jupiter
NASA launched the two Voyager spacecraft to Jupiter, Saturn, Uranus, and Neptune in the late summer of 1977. Voyager 1's closest approach to Jupiter occurred March 5, 1979. Voyager 2's closest approach was July 9, 1979. http://voyager.jpl.nasa.gov/science/jupiter.html (Added: Mon Oct 28 2002)
