History of Astronomy
Essential Question How do astronomers learn what is beyond our atmosphere? Todays Objectives: – Explain geocentric and heliocentric models of solar system – Describe history of Astronomy
Before We Begin… Planets Solar System Solar System Galaxy Galaxies Universe
Early Greek Astronomers Ptolemy Geocentric Model – states that the Earth is the center of everything in universe Planets move in perfect circles around the Earth
Copernicus 1500s Polish astronomer Heliocentric Model – states that the Sun is the center of the universe Planets move in perfect circles around the Sun
Galileo Late 1500s - early 1600s Believed Heliocentric Model Inventor of telescope – Observed moons of Jupiter – Observed phases of Venus
Kepler Late 1500s, German mathematician Planets have elliptical orbits Unable to explain why planets orbits were elliptical
Newton 1600s-1700s Studied Gravity – developed Universal Law of Gravitation Explained why planets orbit in ellipses
Einstein Physicist, early 1900s Theory of Relativity E= mc 2 Energy = (Mass)(Speed of light) 2
Super Models Unit *Scientists*
Famous Astronomers. Ptolemy Thought the Earth was at the center of the universe and that the other planets revolved around it (GEOcentric model) Thought.
Early Models of the Universe. Pythagoreans (500 B.C.) Believed the stars, planets, sun, and moon were attached to crystalline spheres which rotated around.
Read the page Turn the page Go back Research and describe the contributions of scientists to our changing understanding of astronomy, including Ptolemy,
Models of the Solar System. The observations that you have been making of the Sun, Moon and stars were the same observations made by early scientists.
Astronomy- The Original Science Imagine that it is 5,000 years ago. Clocks and modern calendars have not been invented. How would you tell time or know.
Intro to Astronomy Through the early history of civilization, people made observations about the night sky, sun, and moon. They tried to explain what they.
Introduction to Astronomy. How big, and small, is our universe, and how do scientists measure these vast differences? Scientific Notation—a convenient.
Web 1 Ancient Theories of Solar System 1.heliocentric theory 2. geocentric theory 3. Aristotle 4. Aristarchus 5. Ptolemy 6. Copernicus 7. Johannes Kepler.
Geocentric vs. Heliocentric
Chapter 2: The Rise of Astronomy. Ancient Roots: Early Homo-Sapiens.
Developing a Model of the Solar System THE HISTORY OF ASTRONOMY.
Observing the Solar System Section Early Observations Greek Observations Saw star patterns in the sky travel together (Constellations)
Observing the Solar System
Observing the Solar System: A History
Chapter 26.2: Observing the Solar System
RAP 1.1._____wind belt the United States is in 2.2._____rotating column of air that forms over warm ocean water 3.3._____ type of pressure that warm air.
Observing the Solar System. Observers in Ancient Greece noticed that although the stars seemed to move, they stayed in the same position relative to one.
The Solar System Explorers. Ancient Greeks The ancient greeks noticed that the stars would move across the sky, but would stay in the same position relative.
