  1. The Hubble TelescopeBy Elizabeth JohnsonJanuary 20, 2010

  2. FUN FACTS • Hubble telescope is a powerful orbiting telescope that gives great images from space. • It is about the size of a large tractor-trailer truck. • Hubble whirls around Earth at 5 miles per second. • Hubble finishes 1 orbit around the Earth every 97 minutes. • Hubble travels more than 150 million miles (241 million km) per year.

  3. HISTORY • The telescope is named afterAmerican astronomer EdwinPowell Hubble, who made bigdonations to astronomy inthe 1920's. • The space shuttle Discovery launched the Hubble telescope into orbit in 1990. • More than 6,000 scientific articles have been published based on information taken by Hubble.

  4. QUESTIONS AND ANSWERS • 1. Did Hubble find a new solar system? • Yes, Hubble has found other planets in other solar system that has Sodium, Hydrogen, Carbon and Oxygen. 2. How is the Hubble telescope different from land telescopes? • Hubble can take pictures from the atmosphere with better view. Land telescopes cannot see through earth’s thick and polluted atmosphere . 3. Does the Hubble telescope work everywhere? • No, it doesn’t work near the sun because the strong light and heat would fry its sensitive instruments. So, it is always pointed away from the sun.

  5. ImportantDiscoveries • Hubble has helped astronomers calculate the age of the universe to be 13 – 14 billion years old. • Hubble has captured pictures that helped astronomers figure out what the early universe looked like. • Hubble has helped astronomers to sample other planets to see if they are habitable or not. • Hubble explained that the ‘black scars’ on Jupiter was from large chunks of a comet hitting Jupiter. • Hubble has helped NASA find black holes that are billion times heavier than the sun.

  6. End I hope you learned a lot about the Hubble Telescope.
