伽利略观测的准确性和对恒星视差的早期探索
The Accuracy of Galileo's Observations and the Early Search for Stellar Parallax
摘要：
对于17世纪的天文学家来说，年度恒星视差的问题通常被认为是一个“双赢局面”，他们赞同哥白尼的宇宙观，即地球绕太阳运行，太阳是散布在太空中的许多太阳（恒星）之一。探测到视差将是地球运动的确凿证据，但未能探测到视差可以解释为恒星位于很远的距离。最近的工作有关伽利略的意见双星说明伽利略的技能作为一个观察员。这也表明，鉴于当时的光学知识，伽利略可以预期他的测量足够精确，如果存在恒星视差，他们就会发现恒星视差。因此，视差怪并不是一个“双赢的局面”。这可能是反对地球运动的确凿证据，幸运的是，这些证据并没有使伽利略放弃哥白尼的观点。
英文摘要：
The question of annual stellar parallax is usually viewed as having been a "win-win situation" for seventeenth-century astronomers who subscribed to the Copernican view of universe in which the Earth orbits the Sun and the Sun is one of many suns (the fixed stars) scattered throughout space. Detecting parallax would be solid evidence for the Earth's motion, but failure to detect parallax could be explained by the stars lying at great distances. Recent work pertaining to Galileo's observations of double stars illustrates Galileo's skill as an observer. It also indicates that, given the knowledge of optics of the time, Galileo could expect his measurements to be accurate enough that they would have revealed stellar parallax had it existed. Thus parallax was not a "win-win situation" after all. It could be solid evidence against the Earth's motion, evidence which fortunately did not dissuade Galileo from the Copernican view.
