Grade 6 Astronomy

  1. 1. Hubble Space Telescope By:Aisha
  2. 2. This is the Hubble space Telescope that goes around in space taking pictures and sending information back to Earth,
  3. 3. The Telescope <ul><li>The Hubble space telescope was launched on April 25, 19 1990. It was named after the inventor, Edwin Powell, an American astronomer. The telescope has a 7.9-foot mirror that allows it to make observations twenty-four hours a day. The mirror is always clear and has perfect vision. </li></ul><ul><li>Weight: 24,500 lb </li></ul><ul><li>Maximum Diameter: 14 ft </li></ul><ul><li>Length: 43.5 ft. </li></ul><ul><li>Hubble is nearly the size of a large school bus—but it can fit inside a space shuttle cargo bay. </li></ul>
  4. 4. This is the Hubble inside the space shuttle cargo bay. As I said earlier Hubble is as big as a school bus but it can still fit inside a space shuttle cargo bay.
  5. 5. The Telescope <ul><li>The amount that had to be paid to send this telescope to launch was approximately $1.5 billion. </li></ul><ul><li>Construction of the Hubble started in 1977 and finished in 1985. when the Hubble was launched the first pictures weren’t so great but then they figured out why . </li></ul><ul><li>In 1993 they had corrected the problem and the pictures were much better. They hoped for a very good 10 years and hoped that these pictures would answer their questions. </li></ul>
  6. 6. These are some of the pictures that Hubble had taken and that answered some of the astronomer’s questions.
  7. 7. What could cause Hubble to fail? <ul><li>Hubble depends on the batteries and the gyroscopes, but if one of them doesn’t work then the Hubble is no use to us anymore unless we can fix it. But it will be really hard to do that. </li></ul><ul><li>Gyroscopes are the one that point the telescope and keep it stable. If too many fail then Hubble is no use. Hubble has a total of 6 gyroscopes, and 2 are currently broken. But it is fine, as long as all 6 of them don’t break then we are fine. </li></ul><ul><li>Hubble uses a set of rechargeable nickel-hydrogen batteries that are recharged by Hubble’s solar panels. The batteries’ job are to keep the telescope pointed during the night and if the batteries die out, then it could only be pointed for a single day. Nobody knows how long they will last for. </li></ul>
  8. 8. Galaxy Evoloution <ul><li>This was one of Hubble’s discoveries. </li></ul><ul><li>Hubble has discovered that early galaxies were much smaller and more irregularly shaped than they are now. </li></ul>
  9. 9. Age of Universe <ul><li>This is another one of Hubble’s discoveries. </li></ul><ul><li>Hubble observations allowed astronomers to determine an age of the universe using two different methods. </li></ul><ul><li>The universe is 12-14 billion years old. </li></ul>This is the picture of the age of universe.
  10. 10. Black Holes <ul><li>Another discovery of Hubble!!!!!!!!!!!! </li></ul><ul><li>Hubble provided evidence that supermassive black holes do exist. </li></ul>This is a picture of a black hole.
  11. 11. Planets <ul><li>One of Hubble's discoveries again. </li></ul><ul><li>Hubble provided visual proof that raw material for planets, dust disks, are common around young stars. </li></ul><ul><li>Hubble also enabled the detection of a planet orbiting a star outside of our solar system </li></ul>This is one of the 9 planets, Jupiter.
  12. 12. Hubble’s Future <ul><li>If Hubble is not upgraded again, then would have died out in 2006, 2007. The next telescope would be the James Webb telescope and it will be will launched in 2011. It can see as sharply as Hubble. It will be studying the origins of the universe. </li></ul><ul><li>. </li></ul>This is the James Webb telescope and even though it is still in progress, you can see the basic outline of it.
