A trip to Jupiter

Jupiter

Jupiter, it's red spot, and the Galilean moons
(from top) Io, Europa, Ganymede and Callisto.

Last night Kathy managed to stay awake after dark and headed on down to Denny's observatory for the first time to take a look at Jupiter. We have been watching Jupiter for quite a while now and Denny offered to let us take a peek through his telescope. Kathy was able to make out four of Jupiter's moons and assumed they were the same four that Galileo discovered long about 1610. They are shown above in composite next to Jupiter. Kathy was also able to see two of Jupiter's rings.

Jupiter has a large red spot that is the size of 2-3 Earths and is a storm that has been raging over the planet for hundreds of years and will continue for the foreseeable future.

We also took a look at the moon with some close-ups of some of its craters. It was a very unexciting gray color.

Thanks, Denny, for the tour!
