He also constructed a telescope and supported the Copernican theory which supports a sun-centered Solar System. Galileo was accused twice of heresy by the church for his beliefs and wrote a number of boks on his ideas.         In July 1609, Galileo Galilei learned about a simple telescope built by Dutch eyeglass makers and soon developed one of his own.
