![]() These early telescopes were a type of ‘opera glass,’ which produced erect or right side up images. ![]() With these powerful telescopes, he made observations in the Milky Way, of the mountains on the Moon, the phases of Venus, and the moons in the planet Jupiter. Galileo made sense of it in the early 1600s, and he made improvements in lens grinding that did increase the magnification from a relatively low value of two to as much as thirty. The patent was denied because of easy telescope duplication, and there was difficulty in the process of patent enforcement. The first mention of a telescope happens in a letter written in 1608, by Hans Lippershey, who was a Dutch spectacle maker in the process of seeking a patent for a telescope. Telescopes enable you to absorb and analyse radiation from astronomical phenomena, including those that are far apart in the cosmos.Įyeglass-makers had been experimenting with lenses before 1600. The telescope is the most important research tool in astronomy. The first practical telescopes were refracting telescopes with glass lenses, which Galileo discovered in the Netherlands at the beginning of the 17th century. It may also be used to observe distant objects using electromagnetic radiation emission, absorption, or reflection. A telescope is an optical device that observes distant objects using lenses, curved mirrors, or a combination of the two. The first telescope's invention is a bit hazy. Telescope, is an instrument used to form magnified images of distant particles. The word ‘Telescope’ was coined by Giovanni Demisiani in 1611. Given the mysterious beauty of the boundless cosmos, there’s no doubt that telescopes are in the middle of the most fascinating instruments in the field of science.
