| As the anniversary of Galileo's birth, February 15th is the perfect day to tip your telescope to the man largely considered to be "the father of modern observational astronomy." Galileo's list of scientific accomplishments and inventions is daunting and covers a wide range of disciplines. In terms of astronomy, his most astounding contributions began in 1609 when he made remarkable improvements to a simple Dutch spyglass that was at the time awaiting patent. Even though he had not seen the rumored device, he reasoned out how it would operate and created his own 3x telescope. Eventually his experiments led to larger magnification capabilities. Using the scopes he designed, Galileo made many notable observations including discovering four of Jupiter's largest moons, providing proof that Venus had phases and revealing that the Moon's surface was not smooth but was instead a topographical treat that he went on to chart. He observed sunspots and confirmed that the heavens held vast amounts of stars that the naked eye could not discern.
