Galileo's Daughter: A Historical Memoir of Science, Faith, and Love is a book by Dava Sobel published in 1999.

Written in endearing tones and using complimentary titles to address him, Maria Celeste's letters show the great love and respect she had for her father.

But the letters between Maria Celeste and Galileo served more than to maintain contact – she also had a genuine interest in her father's scientific work, sometimes even offering her own opinion on an issue.

Additionally, Galileo's personal life is glimpsed as he and his daughter discuss various details regarding the running of the household, remedies for health and other family matters.

Following inquisitorial hearings, Galileo's work was condemned for violating conditions on the original permission to publish and for proposing heliocentrism as reality rather than as hypothesis.

In addition to Galileo's well-known enhancements and use of the telescope and his conviction of the correctness of the Copernican system, he had many other scientific achievements.
