When Galileo turned his telescope to observe Jupiter, he saw what he initially thought to be three previously unobserved fixed stars. From top to bottom, the moons shown are Io, Europa, Ganymede, and Callisto. Before he left Padua he had discovered the puzzling appearance of Saturn, later to be shown as caused by a ring surrounding it, and in Florence he discovered that Venus goes through phases just as the Moon does.

Some welcomed his observations while others dismissed the discovery of Jupiters moons, attributing them to defects in Galileos telescope. The statement: "An object in motion will continue in motion unless acted on by an outside force." Galileo Galilei (article) | Khan Academy A charge of 20.2C20.2 \mu \mathrm{C}20.2C is held fixed at the origin. And after viewing them over the course of several nights he observed that they moved. Galileo went on to make many telescopes and to make many other important observations in both the night and day sky including the discovery of spots on the sun and the discovery of the rings of Saturn. This was an astonishingly important revelation in our view of the universe because it was previously believed that the moon was a smooth surfaced object. His work on forces was to help Newton develop his dynamics. He drew and described them as handles on the side of the planet and so the mystery remained.

Johannes Kepler wrote a letter of support the following month while additional observations by other astronomers confirmed Galileos claims. Design & Development: A devout Roman Catholic, Galileo had wanted to join the priesthood but, at the age of 16, his father persuaded him to study for a medical degree instead. Galileo didnt stop there. If the masses of both Earth and the Moon became twice as large, the force of gravity experienced by each would. This is not a story of a lone thinker theorizing and piecing together a new model of the cosmos. he also made observations of sunspots. Monitoring these spots on the sun demonstrated that the sun in fact rotated. My dear Kepler, I wish that we might laugh at the remarkable stupidity of the common herd. He also found some ingenious theorems on centres of gravity (again, circulated in manuscript) that brought him recognition among mathematicians and the patronage of Guidobaldo del Monte (15451607), a nobleman and author of several important works on mechanics.

Accused of heresy, he stood trial in early 1633 and, after being found guilty in June that same year, his book was banned and he was sentenced to house arrest. We now know that Galileo was observing the rings of Saturn, but his telescope was not good enough to show them as more than extensions on either side of the planet. But it was with this Galileo Galileis telescope that he began to uncover the true nature of the universe. This design, however, went unbuilt until after the construction of the first working pendulum clock by Christiaan Huygens.
