Night Sky - Page 21

The term "Night Sky" refers to the expanse of the atmosphere observed from the surface of the Earth during nighttime. It encompasses all celestial objects visible after dusk, including stars, planets, moons, galaxies, and other astronomical phenomena. The night sky is characterized by the absence of sunlight, allowing for the visibility of these objects, which can vary in brightness and color due to different factors like distance, size, and composition. The appearance of the night sky can also be influenced by atmospheric conditions, light pollution, and the geographic location from which it is viewed. Observing the night sky has long been a subject of fascination and study in various fields, including astronomy, art, and navigation.
