"별" (pronounced "byeol") is the Korean word for "star." Stars are luminous celestial bodies made up of gas, primarily hydrogen and helium, that produce light and heat through nuclear fusion. They are found in galaxies, including our own Milky Way, and vary in size, brightness, and color. In Korean culture, stars often symbolize hope and dreams. They are frequently referenced in literature, music, and art. The night sky filled with stars can evoke feelings of wonder and inspiration, making them a popular subject in various forms of expression, including traditional Korean poetry and modern songs.
