Jupiter's Moon Ganymede!

By: Jacob Barnes 3rd Period

Its discovery

Ganymede was first discovered by a man named Galileo Galile. He discovered this moon on 7 January 1610. This was the very first discovery of a moon that was not orbiting earth, and at the time this was a very big discovery. Soon we also had figured out that this moon was also the largest moon that is in our solar system.

Spacecraft images of Ganymede show the moon has a complex geological history. Many images show deep groves or "cuts" so to speak in its surface which may be canyons or valleys big enough to see from space. It shows lots of shadow like areas that indicates there is a possibility of clusters of mountains or mountain ranges.

Life on ganymede?!?

One of the things that really gets scientists wondering is the idea of ganymede having a possible source of life. Of course it’s a long shot but there may be some small bacteria in the mantel that scientists believe to be made up of water. These life forms may or may not be there but if they are it is likely to see things in the form of bacteria or jellyfish like creatures. Meaning that these things probably do not have u.f.o’s or ray guns, but it would be interesting to find out one day.

Life on ganymede?!? Cont.

Above you are some simple guesses of what life may be like on ganymede. These creatures would have to see in the dark (if they see at all) and find their oxygen in their water like a fish! They are guessed to be the size of a small plankton and are more plant like than animal like. These creatures most likely would feed off of nutrients in the saltwater or from their fellow bacteria...

In comparison to the earth ganymede is not all that much smaller than the earth. And what makes this moon even more odd is that it has its own magnetic fields just like earth and may and this may be because of having convection currents in its mantel which also leads to the theory that ganymede may have tectonic plate movements.

This is a good example of what scientists are talking about when they say they have seen “grooves” or “cuts on the surface. It is a theory that Ganymede’s surface is being moved by tectonic plates that are floating on a saltwater abyss. Scientists believe that the tectonic plate action has been going on in ganymede for thousands and thousands of years!
