Detailed explanation-1: -Evolution of the optical telescope The reflecting telescope was developed in 1668 by Newton, though John Gregory had independently conceived of an alternative reflector design in 1663. Cassegrain introduced another variation of the reflector in 1672.
Detailed explanation-2: -Early telescopes showed that Earth was not the center of the universe, as was previously believed. They also showed mountains and craters on the moon. Later telescopes have revealed geography and weather on the planets in our solar system. Telescopes have also revealed new planets and asteroids.
