To find the answer, we need to think of the names of American astronomers with six letters. Here are a few possibilities:
1. Carl Sagan: An American astronomer known for popularizing science and his contributions to the study of extraterrestrial life. However, the space telescope was not named after him.
2. Edwin Hubble: Another American astronomer who made important discoveries about the expansion of the universe. However, the space telescope was not named after him either.
3. Nancy Roman: This is the correct answer. Nancy Roman was an American astronomer who played a crucial role in the development of the Hubble Space Telescope. She was often referred to as the "Mother of Hubble" because of her instrumental role in planning and advocating for the project. The telescope was officially named the "Hubble Space Telescope" in her honor.
So, the space telescope was named after Nancy Roman, an American astronomer with six letters in her name.
