If It's about Jupiter, We Have It.

This is an educational page about the planet Jupiter that I (a student at Greensboro Day School) created for a project. I hope you enjoy all of the resources I gather, and all the amazing things you can learn about this intriguing planet.

Permalink Here is a question that many people may have asked themselves- Why does Jupiter have cloud bands? The light loud bands are warmer than the dark. They result from Jupiter’s rapid rotation and convection. The brighter zones are where air is rising in Jupiter’s atmosphere, and the darker zones are where air is descending. This is also caused because of Jupiter’s interior heat.
Permalink Did you know that Jupiter has a magnetic field? Since Jupiter is a Jovian planet, it’s easy to think otherwise due to the lack of an iron core. However, the weird thing about Jupiter is that since it is made of 86.1% molecular hydrogen, the highly compressed hydrogen at the core begins to act as a metal.

List of (most of) The Jupiter Moons

Here is a list of a lot of the Jupiter moons, 63! The four that I have pictures of are the largest. This page depresses me because no one seems to have pictures of the smaller moons.

Permalink This is the Great Red Spot on Jupiter, the biggest anti-cyclonic storm in the solar system, over 40,000km in diameter! I wish you could see the scale of this thing, or it projected on a really huge screen, because this storm is bigger than planet Earth. It has been there since Galileo first looked at it through his telescope in the 1600’s. It has literally been there since we could see it. Scientists think it lasts so long because it never travels over land, unlike Earth hurricanes. I think this is the coolest part of Jupiter, since a storm could last 400+ years. It’s insane.
Permalink Here is an example of the notes the famed scientist Galileo Galilei took when he was observing the moons of Jupiter.
Permalink Galileo Galilei
This sexy man is the one we credit our first knowledge of Jupiter to. When he trained his telescope on the sky on (we think) January 7th, 1610, he discovered Jupiter and all four of its most visible moons.
Permalink Here is a picture of the last of the 4 significant Jupiter moons, Callisto. With a history of 4 billion years and a non-renewing surface, this moon has the oldest face in the solar system. It is heavily peppered with craters, rays, and ejecta. It is considered a “long-dead” world, since it has virtually no geological activity.
Permalink Ganymede
This Jupiter moon is the largest satellite in the solar system. It is bigger than Mercury and Pluto, and if it orbited the sun instead of Jupiter it would classify as a planet. Astronomers found a thin oxygen atmosphere on Ganymede in 1996, but it was way too small to support life.
Permalink Io
Although it isn’t the sexiest moon in the solar system, it is a very interesting and significant one. The most volcanically active body in the solar system, the gravitational pull of Jupiter causes the surface (solid ground!) of Io to change by up to 100 m a day. The difference between high and low tide on Earth is only 18 m, and once again I stress, that is for water instead of solid ground. All of this stress on the outside of Io makes the heated liquid inside try to get out any way that it can. This causes the surface of Io to keep renewing itself and changing its face. Very interesting satellite.
