They were the thermoscope, telescope, Phase of Sunspots, craters on the moon, Leaning Tower of Pisa experiment, and discovery of the Milky Way. The thermoscope was an early version of the thermometer. It was also built from a small vase filled with water that was attached to a thin vertically rising pipe, with a large empty glass ball at the top. Although Hans Lippershey invented the first version of the telescope, Galileo made a new version based on description. He made an improved version up t0 30x magnification. The telescope used convergent objective lens and divergent eyepiece lens. He later explored the sky with it. He was able to identify the phases of Venus, craters on the moon, and four moons orbiting Jupiter. The Phases of Venus was identical to the moon. He discovered four moons or satellites. The satellites were later named the Galilean Satellites in honor of Galileo. They are now called Io, Europa, Ganymede, and Callisto. He was one of the first Europeans who observed sunspots correctly. Galileo noticed the moon’s craters. His observations disproved the Aristotelian theory. The moon was not a translucent and perfect sphere. He also improved the Military Compass. The compass offered gunners a new and safer way of evaluating cannons accurately, and enabled them to quickly compute the change of gunpowder for cannonballs. The theory of gravity came, during the Leaning Tower of Pisa Experiment. Balls with the same material,
