10 Interesting Telescope Facts

Telescope Facts tell you about a tool that the people can use to observe the far away object by using the electromagnetic radiation. At the beginning of 17th century, the first known practical telescopes were made in the Netherlands. The instruments featured the glass lenses. Telescope is mainly used for astronomy and terrestrial application. Let’s find out other interesting facts about telescope below:

Telescope Facts 1: the usage of mirror

Mirror was used to create the first reflecting telescope a few decades ago. The people invented different kinds of telescope in 20th century. In 1960s, there was an infrared telescope, while the radio telescopes were invented in 1930s.

Telescope Facts 2: the usage of telescope

Today, the people can use telescope for various purposes. It can be used not only to observe the objects. The people can also apply it for detecting the electromagnetic spectrum.
