Many people believe that Galileo invented the telescope in 1609. Without Galileo’s contributions, modern science would likely be far less advanced. He made many important discoveries and developments in this field. Born in 1564, Galileo is a famous Italian physicist. The invention of the telescope is often attributed to Galileo. The first potential candidate is the most famous. Galileo Galilei: Are We Confident He Created the Telescope? This has allowed us to learn about these objects and study them further. Now, we can see far-away stars, galaxies, and other celestial bodies. However, the invention of the telescope changed all of that. As a result, many ancient cultures lacked the knowledge of space that we have nowadays. This limited our ability to view distant objects. The History Of Telescopesīefore the invention of the telescope, humans had only been able to see things from a distance using their eyes. This light is controlled by lenses, which are referred to as optics. The more light a telescope can gather, the further you will be able to see. ![]() The telescope will gather light and use it to illuminate objects that are far away. How Do Telescopes Work?Ī telescope works by using lenses to focus light onto a small spot where it can be seen. Uranus is the seventh planet of the solar system, meaning that it was less visible than planets that were closer to Earth (the third planet). This planet, which is named after the Greek god of the same name, was discovered in 1781 by William Herschel. Interestingly, Uranus was the first planet that was found via the use of a telescope. For example, you can get telescopes powered by ultraviolet, x-rays, or infrared. There are lots of different varieties of telescopes which use different types of light. Telescopes are still being developed today. Since then, telescopes have become significantly more advanced. The word “telescope” was created by Giovanni Demisiani in 1611. Galileo's best refractor was able to magnify an object 30 times.A telescope is a device used for viewing objects at great distances by magnifying them. The convex lens inside of a refractor is used to spread out the light from the concave lens in order to see a clearer view of a faraway object.Īlthough refractor lens are still used in small telescopes, they are better used in binoculars and gun scopes. The concave lens inside a refractor focuses the light given off by an object into one focus point. There are two lenses inside of a refractor: a concave lens and a convex lens. Refractor telescopes should be no longer than 40 inches in order to be easy to use. ![]() In 1733, an achromatic lens was developed that corrected some of the distortion of the normal refractor lens. The farther apart the lenses are inside of refractor, the clearer the image will be.Īt one point, Johannes Hevelius built a refractor that was 158 feet long and was very difficult to use. The refracting telescope that was used by Galileo was less than 2 inches long. Refractors are outdated because their image can sometimes be distorted and blurred.Īlthough refracting telescopes are seemingly outdated, they are the better option for a beginning sky observer. The largest size of any one lens in a refracting telescope is 1 meter. The largest refracting telescope was built in 1897. The largest refracting telescope in the world is in Wisconsin. Basically a refracting telescope uses an eyepiece and a lens to gather more light in order to construct a brighter and clearer picture of an object. ![]() During the following year, Galileo improved the refracting telescope and used it to study the sky. These types of telescopes were the first to be used and were developed in 1608. A refracting telescope, or refractor, is one that uses lenses to produce an image. ![]()
