Artist's impression of the Galileo's famous telescopes
With his small, homemade telescopes, capable of magnifying objects by a factor of 20, Galileo Galilei made some of mankind’s most astonishing discoveries. He observed stars and nebulae and studied Solar System objects like the Sun, the Moon, Saturn, Jupiter and Venus. Although he did not invent the instrument, it was Galileo who truly made the telescope famous.
