  3. 3.
  4. 4. Earth and Space Based AstronomyCalifornia State Standard 2<br />Wow! Earth and Space Based Astronomy reveal some important things about:<br /><ul><li>The structure and scale (size) of our Milky Way Galaxy
  5. 5. The changes that occur in stars
  6. 6. The changes that occur in galaxies
  7. 7. The changes in the universe over time</li></li></ul><li>Earth and Space Based Astronomy tell us that:<br />2a. Our solar system is located in an outer edge of the disc-shaped, spiral Milky Way Galaxy, which spans 100,000 light years across. <br />We are here<br />100,000 Light Years<br />
  8. 8. Earth and Space Based Astronomytell us that:<br />2b. Galaxies are made of billions of stars and comprise most of the visible mass of the universe. <br />Hey, What about me?<br />I have mass too!<br />
  9. 9. Earth and Space Based Astronomy tell us that:<br />2c. All elements with an atomic number greater than lithium have been formed by nuclear fusion in stars.<br />Kepler’s Supernova 1604.<br />I’m from the BIG BANG! Where you from?<br />
  10. 10. Earth and Space Based Astronomy tell us that:<br />2d. Stars differ in their life cycles and . . . <br />
  11. 11. Earth and Space Based Astronomy<br />2d. Visual, radio, and x-ray telescopes have been used to collect data so that we can understand how stars differ.<br />
  12. 12. Earth and Space Based Astronomy tell us that:<br />2f. Color, brightness and evolution of stars are determined by a balance between gravity and nuclear fusion.<br />G<br />Stella<br />
  13. 13. Earth and Space Based Astronomy tell us that:<br />2g. The red-shift from distant galaxies and the cosmic background radiation support the Big Bang model which suggest that the universe has been expanding for 10 to 20 billion years.<br />Raisin Bread model of the expanding universe<br />
