Jupiter

After a cool and cloudy July, we finally had a few clear skies this week . Set up the telescope and enjoyed some star gazing over the weekend. You can click on the thumbnail to the right and see a photograph I took through the telescope of Jupiter and three moons Io, Europa, and Gannymede.

Eleven times the diameter of Earth, the rotation of this enormous ball of hydrogen and helium is the fastest of all the Solar System's planets, completing a rotation on its axis in slightly less than ten hours; this creates an equatorial bulge easily seen in this photograph. The
Great Red Spot , a turbulent storm, is visible right in the foreground.
