    "abstract": "The question of annual stellar parallax is usually viewed as having been a\n\"win-win situation\" for seventeenth-century astronomers who subscribed to the\nCopernican view of universe in which the Earth orbits the Sun and the Sun is\none of many suns (the fixed stars) scattered throughout space. Detecting\nparallax would be solid evidence for the Earth\u0027s motion, but failure to detect\nparallax could be explained by the stars lying at great distances. Recent work\npertaining to Galileo\u0027s observations of double stars illustrates Galileo\u0027s\nskill as an observer. It also indicates that, given the knowledge of optics of\nthe time, Galileo could expect his measurements to be accurate enough that they\nwould have revealed stellar parallax had it existed. Thus parallax was not a\n\"win-win situation\" after all. It could be solid evidence against the Earth\u0027s\nmotion, evidence which fortunately did not dissuade Galileo from the Copernican\nview.",
