It is not known who first invented the telescope, but Dutch eyeglass maker Hans Lippershey (or Lipperhey) was the first person to patent the telescope in 1608. His device, called a kijker (“looker”), was, according to Hans, able to magnify an image up to three times.
Why is it called a telescope?
A telescope (from the Ancient Greek τῆλε, romanized tele ‘far’ and σκοπεῖν, skopein ‘to look or see’; τηλεσκόπος, teleskopos ‘far-seeing’) is an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, or various devices used to observe distant objects by their emission.
Did you know facts about telescope?
The first telescopes were made using glass lenses. Modern telescopes can detect infrared and radio waves. An observatory is a remote location that houses at least one telescope. The word telescope is derived from Greek words meaning “far” and “to look and see”.
How far can a telescope see?
Still, we can see a great distance into the heavens with a telescope. With just a pair of binoculars, you can view a galaxy that’s 72 million light-years from us. And if you have a good 10-inch reflector telescope, you can even spot the 3C 273 quasar from 2 billion light-years away.
When was telescope invented?
1608
The invention of the telescope Historians are not absolutely sure who invented the telescope, but it is known that in 1608 a Dutch spectacle maker, Hans Lipperhey, announced a new lens-based seeing instrument that made distant objects appear much closer.

How many light-years can telescopes see?
You can attach 9 more zeros to the end of this to get 1 billion light-years and another one for 10 billion light-years. The farthest that Hubble has seen so far is about 10-15 billion light-years away. The farthest area looked at is called the Hubble Deep Field.
What are some fun facts about telescopes?

In the movies, pirates are often seen examining the horizon with a device known as a Pirate Telescope. 3 The Pope. 4 An interesting delivery.
What are the three main functions of a telescope?
Telescopes perform three main functions: light gathering, resolving, and magnifying. [14] The single most important factor in determining how well a telescope will perform is aperture, or the diameter of a telescope’s lens or mirror. Its aperture determines the brightness and sharpness of its images.
When was the first telescope made?
The earliest known illustration of a telescope is actually a drawing done in a letter done in 1609. It was drawn by Giovanbattista Della Porta. The Hubble Space Telescope (HST) travels around the earth at almost 17,000 mph (27,300 km/h), which is just over 22 times faster than the Land Speed World Record for the fastest car ever.
What is the most famous telescope in the world?
The worlds most famous telescope is the Hubble Space Telescope. It was officially launched by NASA in 1990, seven years later than planned. The delays were caused by the light-absorbing mirror not being polished to the right accuracy. This issue was only fully corrected in 1993. 8. Super-fast!
