Q: Which achievements are attributed to Galileo, the Italian astronomer?

All of the above - Galileo Galilei (1564–1642) was a brilliant Italian scientist who made discoveries that changed how we understand the universe. He is known as the father of observational astronomy because of his careful study of stars, planets, and motion. One of Galileo’s main achievements was developing and improving the telescope. With this telescope, he could observe distant objects in the sky that had never been seen clearly before. Using it, he discovered four large moons of Jupiter—Io, Europa, Ganymede, and Callisto. This showed that not everything revolves around the Earth, which was a big step toward proving the heliocentric model. Galileo also studied pendulum motion and realized that the swing of a pendulum is regular and predictable. This discovery led to the use of pendulums in clocks for accurate timekeeping. Other important work includes observing sunspots, phases of Venus, and the Moon’s surface, which helped people understand that the universe is not perfect and unchanging. In short, Galileo made multiple discoveries that contributed to astronomy, physics, and everyday science knowledge. His work is still important today for understanding motion, time, and the structure of the universe. The correct answer is All of the above, as Galileo developed the telescope, discovered Jupiter’s moons, and studied pendulum motion for time measurement. His achievements are a perfect example of Everyday Science, helping students learn about the natural world and scientific observation.
