Intro.: A Moment in Time with Dan Roberts.

Content: In 1540, a student and supporter of Copernicus, Rheticus, published Naratio Prima, otherwise known as A First Account. This encouraged the aging astronomer to print his own theory. A devout Catholic, Copernicus had struggled for many years between his loyalty to the Church and his scientific theory that asserted heliocentrism, that the sun was the center of the solar system. He decided it was finally time for the world to hear his opinion of the truth. Three years later, just prior to his death, Copernicus published his treatise De revolutionibus orbium coelestium.
