It collects the light from the object and enlarges the picture using the lense, in other words, the glass at the end focuses on that object so you many see it better.
It has allowed astronomers to find out more about the universe, creating clearer more detailed images, also allowing them to look further into the universe to see things such as distant galaxies, stars and planets.

lol probably another lighthouse on a distant island
Telescope eyepieces are important of any visual telescope. It is the main part of the telescope and is what determines how the object will look like through the telescope.
Because it doesn't have to look through any air to see the things it wants to see.
Note that Galileo did not invent the telescope. He was, however, the first person to use a telescope to examine the heavens. Previously, telescopes had only been used to look at distant locations here on Earth.
The telescope has an object lens at the top, which is a large lens with a long focal length. It produces an inverted image of a distant obect at the focal point. The eyepiece is a smaller lens, and you look through the eyepice at the image formed by the object lens. The image is formed in space, it does not need a screen, and you can see it with the eyepiece. The ratio of the focal lengths of the two lenses is the linear magnification.
A tool you hold against your eye to make objects look bigger
If you know exactly where to look, you can see Uranus, but it looks like a very faint star. Saturn is the most distant one you can see easily.
Your telescope will not be directly pointing at an object, and since the night sky is black, your view will be black!
We observe the universe with our various telescopes. Since light travels at a finite speed, it takes time for any light to travel from an object (say, a galaxy), to your telescope. Therefore, for any distant object, you are not seeing the object as it appears now, but as it appeared when the light left it.For very distant objects this can be billions of years, and further back in time you look, the more different the universe appears. Beyond about 13 billion years, there are no galaxies, for example.
A telescope must gather large amounts of light from a dim, distant object; therefore, it needs a largeobjective lens to gather as much light as possible and bring it to a bright focus. Because the objective lens is large, it brings the image of the object to a focus at some distance away
