8th Grade-Ch. 4 Sec. 1 Telescopes

  1. 1. Ch. 4 Sec. 1 Telescopes
  2. 2. telescope <ul><li>device that makes distant objects appear to be closer </li></ul>
  3. 3. electro- magnetic radiation radio waves infrared radiation visible light ultraviolet radiation (UV) X-rays gamma rays light you can see energy that can travel thru space in form of waves
  4. 4. white light passing through prism is dispersed to make a spectrum of colors w/ different wavelengths: red , orange , yellow , green , blue , violet
  5. 5. wavelength <ul><li>distance between crest of one wave & </li></ul><ul><li>crest of next wave </li></ul>
  6. 6. Includes radio waves, infrared radiation, visible light, UV radiation, X-rays & gamma rays electromagnetic spectrum
  7. 7. radio telescope Optical (visible light) radio x-ray collect & focus electromagnetic radiation refracting convex lenses reflecting mirror radio waves
  8. 8. Arecibo radio telescope
  9. 10. 4 Views of the Crab Nebula
  10. 11. Reflecting telescope 1 st Built by Isaac Newton Refracting Telescope
  11. 12. Refracting Telescope
  12. 13. How Telescopes Work Video Clip

  14. 15. Most large observatories are built on top of mountains. Mauna Kea Observatory
  15. 16. Mauna Kea Observatory sits near the 14,000 ft. summit of an extinct volcano in Hawaii. It experiences some of the driest air and best seeing in the world. NASA Kids video-Mauna Kea Observatory
  16. 17. Chandra X-Ray Observatory <ul><li>space based (above Earth) </li></ul>NASA Kids video-Chandra Observatory
  17. 18. ?!?!?!?!?!
  18. 19. <ul><li>reflecting telescope </li></ul><ul><li>diameter of mirror = 2.4 m </li></ul><ul><li>space based </li></ul>Hubble Space Telescope (HST)
  19. 20. Understanding the Universe: The Hubble Space Telescope video
  20. 21. <ul><li>HST was launched in 1990 from the Space Shuttle and orbits approximately 600 km above the Earth's surface. </li></ul><ul><li>Cost ing over $1.5 billion , it is the most expensive scientific instrument ever built. </li></ul><ul><li>Unfortunately, the reflecting mirror that HST used was not made correctly , which caused distorted images to be produced. </li></ul><ul><li>A later repair mission with the Space Shuttle put a correcting lens on HST to improve its &quot;eyesight&quot; and it now produces stunning images of unrivaled quality. </li></ul>Hubble Space Telescope orbiting the Earth Astronauts have repaired and upgraded the Hubble Space Telescope on several occasions.
  21. 22. Pictures from the Hubble Space Telescope
  22. 25. <ul><li>launched in 2003 </li></ul><ul><li>infrared images </li></ul>
