Naked-eye observations refer to the ability to see and study objects or phenomena without the use of telescopes, binoculars, or other optical instruments. This method allows individuals to observe celestial bodies like stars, planets, and the Moon directly, making it accessible to everyone. These observations can also include natural events such as weather patterns or animal behavior. By relying solely on their eyesight, people can gather information about their surroundings and the universe, fostering a deeper connection with nature and enhancing their understanding of basic scientific concepts.
