OLD TELESCOPES

Details

The invention of the telescope played an important role in advancing our understanding of Earth's place in the cosmos. While there is evidence that the principles of telescopes were known in the late 16th century, the first telescopes were created in the Netherlands in 1608. Spectacle makers Hans Lippershey & Zacharias Janssen and Jacob Metius independently created telescopes.

  • Telescopes gave rise to the first high-speed telecommunications networks
  • First Telescopes (1608): Invented in the Netherlands by Hans Lippershey and others.
  • Galileo's Telescope (1609): Improved design; magnified up to 20 times.
