The correct answer is the telescope. Using a telescope, Galileo Galilei made a series of astronomical observations that supported the heliocentric theory proposed by Nicolaus Copernicus. To confirm heliocentrism, Galileo observed the phases of Venus, the moons of Jupiter, and the mountains and valleys on the Moon. These observations provided evidence that celestial bodies were orbiting the Sun, rather than Earth being at the center of the universe.
