Hence, prior to the invention of the telescope, nothing was known about the planet besides its position on the sky. The Italian scientist Galileo Galilei was the first person known to use a telescope to make astronomical observations. His records indicate that he began observing Mars through a telescope in September 1610.
Confidence votes 53. Neither Newton nor Galileo invented the telescope. It was developed independently by various dutch optics makers (Lippershey submitted the first patent). Galileo's first telescope was dutch-made, and he made useful improvements to the initial retractor design. Newton did invent the reflecting telescope (the particular design is now called a Newtonian Telescope).
