Jupiter !

Look to the right of the stunning full Harvest Moon and you will see what appears to be a large brilliant star. It is Jupiter at its brightest! Using a simple student telescope, you can easily see Jupiter's stripes and big red spot. Don't stop there! Clearly visible, off to the right of our biggest planet, you'll see two tiny spots. These are Jupiter's moons Ganymede and Callisto. (See Jim Lu's wonderful picture on the left.) Good eyes and telescopes can also see the moon Io just at the right edge of Jupiter itself. Looking for more fun? Slightly higher in the sky and off to the left you can find Uranus asking for your attention. Take a look at the brilliant Harvest Moon while you are at it. I never seem to grow old of looking at it's impact marks, craters and varied topography. What a show tonight!
