Telescope Facts

The list of interesting telescope facts:

  • Ancient China and Ancient Greece were the first to observe different scientific facts of optics between 5th-3rd BC.
  • The exploration of optics in Medieval Europe was founded by the translation of the “Book of Optics” written by an Arab scientist Ibn al-Haytham in the 12th Century.
  • Lens makers of Denmark made simple modern telescopes for the first time.
  • Eyeglasses were made in the 13th century for the first time in Italy.
  • In the 16th century, the first modern telescope was invented by Dutch spectacle-maker Hans Lippershey.
  • The early use of the telescope was to look for other friendly or enemy ships by the crews on merchant ships.
  • In the 17-19th centuries, the military used telescopes for the first time to track troop movements.
  • Galileo became popular as his patent was acknowledged by the Royal Society and the European Scientific. However, Issac Newton could make a more powerful scope feasible for scientific use. 
  • Well-known physicists, astronomers, mathematicians, engineers, etc played pivotal roles in the development of telescopes, for example, Galileo Galilei, Johannes Kepler, Christian Huygens, Isaac Newton, and others.
  • The idea of sending a telescope to space was proposed in 1923 and ‘The Hubble Telescope’ was the first space telescope that was launched from the earth in 1970.
  • ‘The Hubble Telescope’ transmits 120 GB of data every week engendered 25% of space images used in all modern research papers so far.
  • The operational cost of ‘The Hubble Telescope’ is more than 10 billion dollars now.
  • The sizes of telescopes can vary from some inches to a large football field.
  • The best place for large telescopes is the top of mountains for several reasons like no city light pollution, no flickering of light due to thick clouds, etc.
  • The largest telescope is the “European Extremely Large Telescope” having a primary mirror with a diameter of 39.3m. The second most giant telescope is the “Thirty Meter Telescope” located on Hawaii island.
  • All modern telescopes are connected to the internet so that astronomers from anywhere in the world can access their data and use them remotely.
  • Telescopes are of different types depending on the mount and optical design or the observing electromagnetic spectrum (Radio, X-Ray, Optical, Gamma-ray, high-energy particle telescopes).
  • The James Webb Space Telescope is the perfect successor to the Hubble telescope with larger mirrors and more light-gathering power.
  • A large array of telescopes can be connected together to collect lights or signals from far distances. Very Large Array (VLA) in New Mexico is a telescope of that type with 27 antennae occupying a diameter of 25 m.
