THE VERY RARE ORIGINAL EDITION ON LARGE PAPER, which was reprinted by Kepler in the same year at Prague. 



It contains the first-fruits of Galileo's astronomical investigations with his newly invented telescope, which enabled 

 him to discover mountains and valleys on the surface of the moon (hitherto considered to be smooth), also that the moon 

 was not self-luminous, but only reflected the light received by the sun. 



The most important discovery it contains however is that of the four satellites of Jupiter, called by him Medicean 

 Stars, in honour of the family of his protector. Their different position at different times induced him finally to accept 

 the Copernican theory. He also found that the Milky Way is composed of countless separate stars, etc. etc. etc.
