I believe the name of the first telescope was called the "telescope." The word was created from the Greek tele = 'far' and skopein = 'to look or see'; teleskopos = 'far-seeing'.
Telescopes were first used in 1952 by Oxford scientist Ron L. Hubbard--his predecessor, Mallory Hieney, first saw the planets with his device. Its called a fefracting telescope.

It doesn't have to be big telescopes, there does not even have to be a telescope. It is called an observatory because it is a place where astronomical observations are made. Long before the first telescope was made there were observatories.
The first telescope didn't look exactly like the ones that we see today, but it was improved though by the famous astronomer Galileo. The first one is said to have been made about 500 years ago.
There are two very similar 10-meter telescopes at the W.M. Keck Observatory on Mauna Kea, on the Big Island of Hawaii.

Yes, the earliest telescopes made things look thousand of times closer than they were, and modern telescopes still do that.

That telescope you are refering to is called a refracting telescope.
The largest telescopes that use visible light are reflector telescopes.

Hans Lippershey is credited with inventing the earliest working telescope and applying for a patent for the device. These telescopes appeared in 1608.
Telescopes have been around since 1608, and they have been called "telescopes" the entire time. There is no original word.
No, Galileo did not invent the telescope. According to Wikipedia "The earliest known working telescopes appeared in 1608 and are credited to Hans Lippershey" Galileo was the first person to turn the telescopes to the night sky and make some pretty contradictory observations.

They have changed because now there is a telescope in space called the "Hubble". I can see things that regular telescopes on Earth cannot see.
