After he completed his first reflecting telescope in 1668, Isaac Newton found that he could observe the four Galilean moons of Jupiter – Europa, Ganymede, Io and Callisto – as well as the crescent phase of the second planet from the Sun, Venus. Newton’s intention wasn’t to discover new objects with his telescope.
How Newton’s telescope changed the world?
Sir Isaac and his telescope carried on with the work of Copernicus and Galileo by furthering our understanding of the universe we live in and helping us to realize there are laws that govern the whole of the universe. And this rule holds true for falling apples and for planets revolving around stars.
What are Newtonian telescopes used for?
Newtonian telescopes are reflectors. They use a mirror, rather than a lens, to focus light from distant objects. Reflecting telescopes were first invented by Isaac Newton to avoid the problems of chromatic aberration found with refractors.
Why was the reflecting telescope important?
It was invented during the 1680s by Isaac Newton. These telescopes improved the before used refracting telescopes by giving a clearer picture. Reflecting telescopes also allow larger objects to be seen and are therefore ideal for studying objects in our Solar System.
What was Isaac Newton’s most important discovery?
What is Isaac Newton most famous for? Although Isaac Newton is well known for his discoveries in optics (white light composition) and mathematics (calculus), it is his formulation of the three laws of motion—the basic principles of modern physics—for which he is most famous.
How does a Newtonian reflector work?
Newtonian Reflectors, including the Dobsonian (Dob), have a concave spherical or parabolic primary mirror at the back of the telescope that collects and focuses incoming light onto a flat secondary (diagonal) mirror.
Who invented the Newtonian telescope?
Isaac Newton (1642-1727, F.R.S. 1672, P.R.S. 1703-1727) is generally I credited with the invention of the reflecting telescope, having conceived the idea in 1666* (1, 2, 3).

What is Newtonian focus?
Quick Reference. A focal position for a reflecting telescope at the side of its tube, at right angles to the incoming light. Light reflected from the main mirror is diverted to the Newtonian focus by a flat diagonal mirror, or a prism, higher up inside the tube.
When was the Newtonian telescope invented?
The reflecting telescope was developed in 1668 by Newton, though John Gregory had independently conceived of an alternative reflector design in 1663.
Why did Isaac Newton invent the reflector telescope?
Newton built his reflecting telescope because he suspected it could prove his theory that white light is composed of a spectrum of colours. … If this were true, then chromatic aberration could be eliminated by building a telescope which did not use a lens – a reflecting telescope.
What famous scientist first used the telescope for astronomy?
Galileo Galilei (1564-1642) was part of a small group of astronomers who turned telescopes towards the heavens. After hearing about the “Danish perspective glass” in 1609, Galileo constructed his own telescope. He subsequently demonstrated the telescope in Venice.
Who was Isaac Newton’s wife?
He never married. Newton died in 1727, at the age of 84. After his death, his body was moved to a more prominent place in Westminster Abbey.
What were 3 of Isaac Newton’s discoveries?
New Scientist once described Isaac Newton as “the supreme genius and most enigmatic character in the history of science.” His three greatest discoveries — the theory of universal gravitation, the nature of white light and calculus — are the reasons why he is considered such an important figure in the history of science …
How did Isaac Newton discover gravity?
The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature. Whatever really happened, Newton realized that some force must be acting on falling objects like apples because otherwise they would not start moving from rest.
