Galileo Spots Jupiter's Moons
“Padua, January 7, 1610, night. Galileo records four 'little stars' beside Jupiter through his telescope on a small balcony. Foreground shows a long brass spyglass on a tripod and a sketchbook open with ink dots labeled I, II, III, IV; midground reveals the astronomer in fur-trimmed scholar's robes wrapped against the cold; the winter sky blazes with stars above Renaissance rooftops.”
