The telescope was invented by Galileo. He constructed his first telescope in 1609, significantly improving upon existing designs to magnify distant objects. Galileo’s observations revolutionized astronomy, leading to discoveries such as the moons of Jupiter and the phases of Venus, which supported the heliocentric model of the solar system.

Galileo Galilei, an Italian astronomer and physicist, is credited with inventing the telescope around 1609. The correct answer is [A] Galileo. Galileo’s telescope was a significant improvement over existing designs, allowing him to observe celestial objects with greater detail and clarity. His observations, including the phases of Venus and the moons of Jupiter, provided compelling evidence for the heliocentric model of the solar system proposed by Copernicus. This revolutionary instrument fundamentally changed our understanding of the universe and paved the way for modern astronomy. Johannes Gutenberg (option B) invented the printing press, Thomas Edison (option C) invented the phonograph and electric light bulb, and Alexander Graham Bell (option D) invented the telephone, none of which are related to the invention of the telescope. Thus, Galileo Galilei remains widely recognized as the inventor of the telescope and a key figure in the history of science.
