Sixteen years after his first encounter with the church Galileo published his "Dialogue on the Two World Systems" in 1632, and the pope, Urban VIII, ordered another investigation against him. Galileo also observed the phases of Venus, which proved that the planet orbits the Sun. Galileo, solar observing, and eye safety - San Diego State University Although there is still some controversy about when and by whom sunspots were first observed through the telescope, we can say that Galileo and Thomas Harriot were the first, around the end of 1610; that Johannes and David Fabricius and Christoph Scheiner first observed them in March .
