This telescope was launched into low-earth orbit.

Quick Facts: –

  • The Hubble Space Telescope is the first large, space-based optical telescope of the world.
  • It is a reflecting telescope because it captures images by using mirrors.
  • The HST’s travelling speed is about 5 miles per second.
  • This telescope orbits about 353 miles above earth.
  • Till now, Hubble Space Telescope has made more than 1.2 million observations that include several comets, black holes and planets.

  • After taking pictures of different objects, it uses radio waves to send them through the air back to the earth.
  • It is an unmanned satellite and is controlled from the Earth.
