In doing so, the rings appeared edge-on to us (in 1612) and then re-appeared and widened (as Galileo observed in 1616.). The story of Galileo's telescopic observations illustrates how a tool for seeing and collecting evidence can dramatically change our understanding of the cosmos.

In February 1615, the Church ordered Galileo to abandon his belief in a Sun-centered solar system and one of his books was banned. Select all that apply. In reality, Galileo was observing Saturns rings, but the optics of his telescope were too inferior to show their true nature. This motion is caused by the rotation of the Earth on its axis As a result, Galileo was confirmed in his belief, which he had probably held for decades but which had not been central to his studies, that the Sun is the centre of the universe and that Earth is a planet, as Copernicus had argued. Whats a Galileo telescope? The Hungarian novelist, Zsolt de Harsanyi, is the latest sinner in this matter. have the potential to produce sharper images He speculated that the Milky Way was made up of tiny stars, too small to be seen with the naked eye.

What was Galileo's final punishment for his disagreement with the Catholic Church?
