Galileo's Letters on Sunspots
太陽黒点の研究

1613年に出版された、太陽の黒点の観察によって地球の自転、すなわち地動説を示唆しているガリレオの書籍。
しかし当時、神が創った宇宙のなかで地球は不動と考える天動説が主流であり、この本はガリレオの宗教裁判のきっかけとなった。

Galileo's Letters on Sunspots

This book by Galileo was published in 1613. In it he describes the rotation of the Earth, that is, that the Earth rotates around the sun, based on his observations of sunspots.
Since, however, religious doctrine then held that the Earth created by God was immovable and the sun rotated around the Earth, the publication of this book led to Galileo’s examination by the Inquisition.
