11. Tycho Brahe's Contribution to Astronomy
There was a man who did not believe Ptolemy's version of the universe nor did he believe in Copernicus's views on the universe. Who was this daring man? He was Tycho Brahe. We'll learn about him in this lesson.
12. Kepler's Three Laws of Planetary Motion
Find out about the interesting life and major contributions of Johannes Kepler. This lesson will also teach you how to find out how long it takes a planet to revolve around the sun!
13. Galileo, the Telescope & the Church
This lesson explores the contributions of Galileo to modern science. It examines his early steps toward a scientific method, his work on falling bodies and, of course, his astronomical discoveries. Finally, the Church's reaction to these discoveries is explored.
14. Sir Isaac Newton And Astronomy
This lesson will teach you about Newton's laws of motion and universal gravitation as well as why the moon doesn't fly off into space and why it doesn't crash into the Earth.
15. Origins of the Julian & Gregorian Calendars

17. What is Astronomy? - Definition, History, Timeline & Facts
When you look up at a clear night sky, how many stars do you see? Probably more than you can even count! What's more incredible is just how large and far away those stars are, and how much we can learn about our universe by looking at starlight.
