Lesson Excerpt
The word ?astronomy? comes from the Greek words ?astron? (which means star) and ?nomos? (which means law). Astronomy is the study of celestial objects like stars, planets, galaxies, and comets.

Galileo was credited with improving the telescope, which allowed astronomers to see the celestial bodies more closely. This enabled them to make more accurate observations of celestial bodies like stars.
