Unformatted text preview: Galileo Galilei is known for his ingenuity and drive to prove subjective theories wrong. When Galileo was 40, he heard that a Dutch optician had created glass that made far away objects appear larger and closer. This led to the creation of a telescope. Galileo discovered that the Moon had craters and that the sun has spots. He also proved that Jupiter has its own moons. Galileo lived from 1564 to 1642. Many more discoveries were made.

Galileo felt compelled to take back his claims due to societal pressure. http://antwrp.gsfc.nasa.gov/apod/ap011014.html...
