Galileo's telescope
With cards in time order: [1] 1608: refracting telescopes first appear in the Netherlands; the inventor is unknown, but Hans Lipperhey applies for the first patent; [2] 1609: Galileo hears of the telescope and works out how to build his own (summary in our words); [3] January 1610: Galileo looks at Jupiter. Excerpt (Galileo, The Sidereal Messenger (1610), on Jupiter; English translation by Edward Stafford Carlos, 1880, p. 45): "…the planet Jupiter presented itself to my view, and as I had prepared for myself a very excellent instrument, I noticed a circumstance which I had never been able to notice before, owing to want of power in my other telescope, namely, that three little stars, small but very bright, were near the planet…"; [4] early 1610: Galileo looks at the Moon. Excerpt (Galileo, The Sidereal Messenger (1610), on the Moon; English translation by Edward Stafford Carlos, 1880, p. 15): "…I feel sure that the surface of the Moon is not perfectly smooth, free from inequalities and exactly spherical… but that, on the contrary, it is full of inequalities, uneven, full of hollows and protuberances [bumps], just like the surface of the Earth itself, which is varied everywhere by lofty mountains and deep valleys."; [5] 13 March 1610: Galileo publishes The Sidereal Messenger, reporting the Moon's mountains and four moons of Jupiter. Arrows (this made the next one possible): 1 → 2, 2 → 3, 2 → 4, 3 → 5, 4 → 5. Below the strip: Galileo wrote in Latin. The excerpts are from an 1880 English translation.
