I told him as he gazed into the eyepiece. He had that bored look of a teenager indulging his geeky father once again. Galileo observed this sight with his homemade telescope \u2014 a \u201cspyglass\u201d with two lenses at opposite ends of a tube.39 As noted, Galileo improved telescope now had a magnification of some 20\u00d7.40 He would return to Jupiter\u2019s strange companions on following nights.<\/p>\n

They had moved! On January 10, he observed that one of the small \u201cstars\u201d had disappeared entirely. What was going on? Galileo realized the missing stellar object was now hidden behind Jupiter. He concluded that these were not tiny stars, but three moons orbiting Jupiter \u201clike a planetary system in miniature.\u201d41 These were the moons we now call Io, Europa, and Callisto.* On January 15 he saw a fourth moon, Ganymede.42 He later wrote: Our sense of sight presents to us four satellites circling about Jupiter, like the Moon about the Earth, while the whole system travels over a mighty orbit about the Sun .<\/p>\n

. . \u2014 Galileo, \u201cThe Starry Messenger.\u201d43 By March 2, Galileo had completed sixty-four sightings of Jupiter\u2019s moons.45 He would later describe what he called his \u201cmost important\u201d discovery (see Fig. 22.2): The disclosure of four PLANETS never before seen from the creation of the world up to our time .<\/p>\n

Bottom: Galileo\u2019s drawing from observations using his telescope.44 Galileo astutely named these moons of Jupiter the four Medicean planets in honor of his patron, Cosimo II de\u2019 Medici. The nineteen-year-old had become Grand Duke of Florence after the death of his father Ferdinando a year earlier.<\/p>\n

This is the same Cosimo that Galileo had tutored in previous summers.46 These largest four moons of Jupiter are now referred to as the Galilean satellites in Galileo\u2019s honor.47 Initially \u201cmany astronomers and philosophers refused to believe that Galileo could have discovered such a thing,\u201d writes Dava Sobel.48 Why such doubts?<\/p>\n

Because Galileo\u2019s observations ran against Aristotelian dogma that all celestial bodies revolve around a stationary Earth.<\/p>\n
