499 years ago on the night of December 28th, the astonishing Galileo Galilei fixed his new telescope on Jupiter whose moons he had discovered. An unexpected speck of light transfixed his eye. Some 230 years later, modern astronomers realized that Galileo had noticed the 8th planet…Neptune. Construct a Galileoscope, a working model of the telescope Galileo used. Use your telescope to learn just how keen Galileo's eye was. Discover how an iPhone or iPad can direct your eye (iPhone and iPad not included). Construct a stand for your telescope which becomes a model of the planets. Make a model of Voyager 2. Take a day to know Neptune.
