Galilean Moonshttp://www.worldwidetelescope.org/wwtweb/thumbnail.aspx?name=SolarSystemSince Galileo discovered them, the four
largest moons of Jupiter became
known as the 'Galilean Moons'.http://www.worldwidetelescope.org/wwtweb/thumbnail.aspx?name=SolarSystemIt was Kepler who suggested they be
named for mythological beings
associated with Jupiter.http://www.worldwidetelescope.org/wwtweb/thumbnail.aspx?name=SolarSystemAs their appearance suggests they
have very different properties....http://www.worldwidetelescope.org/wwtweb/thumbnail.aspx?name=SolarSystemMost of the beautiful images we have
were taken by the spacecraft "Galileo"
which visited each in the time from
1995 to 2003.http://www.worldwidetelescope.org/wwtweb/thumbnail.aspx?name=SolarSystemhttp://www.worldwidetelescope.org/wwtweb/thumbnail.aspx?name=SolarSystemIo:
The most volcanic place in the Solar Systemhttp://www.worldwidetelescope.org/wwtweb/thumbnail.aspx?name=SolarSystemhttp://www.worldwidetelescope.org/wwtweb/thumbnail.aspx?name=SolarSystemEuropa:
The Icy moonUnder its icy surface, lies an ocean-
possibly the most promising place for
life to exist outside the earth.http://www.worldwidetelescope.org/wwtweb/thumbnail.aspx?name=SolarSystemhttp://www.worldwidetelescope.org/wwtweb/thumbnail.aspx?name=SolarSystemCalliso:
Tidally locked and heavily cratered.http://www.worldwidetelescope.org/wwtweb/thumbnail.aspx?name=SolarSystemhttp://www.worldwidetelescope.org/wwtweb/thumbnail.aspx?name=SolarSystemGanymede:
Only moon in the solar system to
have a strong magnetic fieldhttp://www.worldwidetelescope.org/wwtweb/thumbnail.aspx?name=SolarSystemhttp://www.worldwidetelescope.org/wwtweb/thumbnail.aspx?name=SolarSystemMany questions remain:
How did the moons form so differently?
What causes the surface features of Ganymede?
Can life exist in the icy oceans of Europa?PNG
