What did Newton discover with his telescope?
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.
Did Newton invent the first telescope?
The first reflecting telescope built by Sir Isaac Newton in 1668 is a landmark in the history of telescopes, being the first known successful reflecting telescope. It was the prototype for a design that later came to be called the Newtonian telescope.
Who invented Newton’s telescope?

How did Newton’s invention of the reflecting telescope affect the field of astronomy?
How did newtons invention of the reflecting telescope affect the field astronomy? It allowed astronomers to see clear images, without distorted or loss colors. According to Newton, what kind of objects are affected by gravity? All objects in the universe.
What was Isaac Newton’s most famous invention?
Gravity: – It is the most famous discovery by Isaac Newton. He outlined this theory in the Principia. His concept of gravitational force also helped in explaining the movements of the planets and the Sun. Calculus: – He invented a completely different type of mathematics.
How does light travel through a Newtonian telescope?
In a Newtonian reflector, light reflects off the mirror and is converged to the focal plane. However, before it reaches the focal plane, it encounters a second mirror at a forty-five-degree angle. This redirects the light into an eyepiece on the side of the telescope.
