  1. 1. By: CC and CM Hubble Space Telescope
  2. 2. How it works <ul><li>Light hits the primary mirror focusing the light beam </li></ul><ul><li>Strikes a secondary mirror which focuses the beam more </li></ul><ul><li>Light beam goes through COSTAR (“contact” lens) to correct for defects </li></ul><ul><li>Light reaches sensor equipment including FOC, NICMOS, STIS </li></ul><ul><li>An image is produced using the data recovered and is sent to earth </li></ul>
  3. 3. A Sharper View on…well Space! <ul><li>5 different instruments </li></ul><ul><li>Wide Field Planetary Camera 2 </li></ul><ul><li>Near Infrared Camera and Multi-Object Spectrometer </li></ul><ul><li>Space Telescope Imaging Spectrograph </li></ul><ul><li>Advanced Camera for Surveys </li></ul><ul><li>Fine Guidance Sensors </li></ul>
  4. 4. The Making <ul><li>Originally was granted funds in 1977 </li></ul><ul><li>Took 8 years to build </li></ul><ul><li>Finally went into orbit in 1990 after a break following the challenger disaster </li></ul><ul><li>Defect in mirror causes Hubble to get “contact” lens </li></ul><ul><li>Hubble continues to send clear images to date and is looking to expand its range with a new finer mirror </li></ul>
  5. 5. A Farther Detailed View <ul><li>Hubble is the farthest clearest visual telescope yet </li></ul><ul><li>Offers a wide range of detailed imaging and wide range of light waves </li></ul>
  6. 6. Spitzer Telescope
  7. 7. Infrared Waves…A New Way to See <ul><li>Spitzer is the largest infrared telescope launched into space </li></ul><ul><li>Offers a way to see infrared waves in clearer detail and wider range in detail where most wave lengths are blocked by earth’s atmosphere </li></ul><ul><li>Originally launched in 2003 </li></ul>
  8. 8. Infrared Sight <ul><li>Spitzer uses a compound telescope designed to reflect and focus infrared waves </li></ul><ul><li>Spitzer’s 3 instruments </li></ul><ul><ul><li>Infrared Array Camera </li></ul></ul><ul><ul><li>Infrared Spectrograph </li></ul></ul><ul><ul><li>Multiband Imaging Photometer </li></ul></ul>
  9. 9. Penetrating Dust Clouds <ul><li>Visuals alone can’t penetrate dense dust clouds that refract light </li></ul><ul><li>Infrared waves do penetrate dust clouds and can be pick up by Spitzer </li></ul><ul><li>It allows scientists to view into some nebula’s and areas where star formations are taking place </li></ul>
  10. 10. Why Use Two? <ul><li>Hubble Telescope is great with clear detail and visual light waves </li></ul><ul><ul><li>It can’t penetrate dust clouds or bright areas </li></ul></ul><ul><li>Spitzer Telescope is great with clear infrared imaging </li></ul><ul><ul><li>Can’t give a detailed visual image </li></ul></ul><ul><li>So use both and combine the images to make a wide spectrum range image </li></ul>
  11. 11. Observing Star Formation (SF) <ul><li>Formation of stars greatly depends on the matter and density </li></ul><ul><li>Places with high star formations are called “Nurseries” </li></ul><ul><li>In these nebulas and dust clouds, stars can form very rapidly </li></ul>
  12. 12. Star Formation Rates <ul><li>Using both Telescopes we can observe areas where stars are forming </li></ul><ul><li>This gives us an estimate on star formation rates compared to size and brightness </li></ul><ul><li>This allows us to see an idea of how the universe and stars might have started out </li></ul>
