As humans, since the dawn of man, we hath gazed into the night sky with wonders of what is beyond our Earth. Stars, moons, planets, galaxies, nebulae, Supernovae, black holes and more are out there in our beautiful universe. But before the telescope, I range of views of what was out there, was limited.
The Naked Eye
Before Telescope, Humans did Astronomy, or Astrology as it was called back then, with the naked eye. Now, do not get it twisted, The Naked Eye is very good for Astronomy. We mapped out calendars and season with it and we have learned alot about space with it. For example we knew of Six planets: Mercury, Veuns, Earth, Mars, Jupiter and Saturn; with the naked eye, we can see the Sun of course, we can see the Moon, Luna, we saw many stars, before light pollution, and more! There is a lot of things we can see in Space without a telescope. And just like any tool, a telescope just enhances our abilities. An axe helps us cut down a tree, a hammer helps us push in a nail, a spear helps us hunt prey & a telescope lets us see more in space.
The First Telescope
Before Telescope, viewing planets like Uranus or seeing exoplanets, was impossible; our eyes, just weren't strong enough to see these astronomical objects. However, in 1608, all of that would change. For in 1608, The Telescope patented. Now our range of Astronomical sight would be enhanced threefold and beyond! The First ever telescope was called a Kijker or Looker. One year later, The World renowned Astronomer, Galileo would build his own version of the telescope. Later with this, he would prove once and for all that The Universe was not Geocentric (Earth Centered), but that, at least our Solar System as we know now, was Heliocentric( Sun Centered).
The Telescope is a device that is an optical instrument that makes distant materials appear magnified like a Microscope makes Microscopic objects appear magnified. This is done using an arrangement of lenses that when out in a certain order, will make the distant object larger in the looking lense. This means that Uranus, being farther than our eyes can see on their own, can now be seen easily using a telescope. There are different types of telescope too.
- Optical Telescopes are Telescopes that use visible light to magnify.
- Ultraviolet Telescope use a shorter wavelength than visible light.
- X-Ray Telescopes use a shorter wavelength than Ultraviolet Light.
- Infrared Telescopes use a longer wavelength than visible Light.
- Submillimeter telescopes use Microwave wavelengths than are longer than infrared light.
- Radio telescopes use the longest wavelengths than the other telescopes.
Telescopes are a crucial part of Today's Astronomy. Without them, a lot of what we know now would have been unknown. Advancement in technology, like telescopes, can be a good things for humanity. For without the spear, hunting prey would be harder, without the axe, cutting down trees would be impossible, without fire, cooking food would be impossible, without a computer, ye would not be reading this write now & without a telescope, we would still believe Earth was the center of The Universe.
