2. In this lesson, you will learn about the history of Astronomy. In this lesson, you will learn about the history of Astronomy. After we view this presentation, you will create a time line of the history of Astronomy. After we view this presentation, you will create a time line of the history of Astronomy.

3. Definition: The scientific study of matter in outer space, especially the positions, dimensions, distribution, motion, composition, energy, and evolution of celestial bodies and phenomena.

4. Aristotle believed that Earth was the center of the universe. He also stated that Earth was made up of only four elements: earth, water, air, and fire. He thought that the other celestial bodies such as the Sun, Moon, and stars, were made up of a fifth element called ether.

5. Ptolemy was a Greek astronomer. He combined his ideas with those of Aristotle and created his own model of the universe. Like Aristotle, Ptolemy also believed that Earth was the center of the universe, and all other heavenly bodies circled it. This view remained intact for over 1,400 years until the time of Copernicus.

6. Hypatia was an Egyptian math and astronomy teacher and is remembered as one of the first female astronomers. In addition to teaching math and astronomy, Hypatia invented several tools relating to astronomy and the Earth sciences Hypatia was an Egyptian math and astronomy teacher and is remembered as one of the first female astronomers.

7. Nicholas Copernicus was a Polish astronomer. He was the first scientist to introduce a model of the Solar System that centered around the Sun. He believed that all the plants, including Earth, moved in orbits around the Sun. Nicholas Copernicus was a Polish astronomer.

8. Tycho Brahe was a Danish astronomer. He is best known for his observations of stars, comets, and planets in the night sky. Tycho also build the first observatory. Tycho’s records were later used by Kepler to describe the orbits of planets. Tycho Brahe was a Danish astronomer. He is best known for his observations of stars, comets, and planets in the night sky. Tycho also build the first observatory. Tycho’s records were later used by Kepler to describe the orbits of planets.

9. Johan Kepler was a German astronomer. Kepler used Brahe’s records to show that planetary orbits are not circular, but elliptical (or shaped like an egg). He was able to prove this theory about planetary motion. As a result, he helped prove that the Copernican model of the universe was correct. Johan Kepler was a German astronomer.

10. Galileo Galilei was an Italian astronomer and physicist. He was the first scientist to use a telescope to study the night sky and Jupiter’s moons. Galileo was also one of the first scientists to report that there were craters on the Moon and spots on the Sun. Galileo Galilei was an Italian astronomer and physicist.

11. Sir Isaac Newton was an English scientist and mathematician. He was one of the most notable scholars of his time. Newton developed several laws that help us understand the movement of objects. As the story goes, Newton was inspired to create his theory of gravity after he watched an apple fall to the ground. Sir Isaac Newton was an English scientist and mathematician.

12. Caroline Herschel was a German astronomer. She and her brother, William Herschel, discovered three new nebulae (clouds of space dust) and eight comets. She also wrote books on astronomy.
