skyglow

Skyglow is the brightening of the night sky over populated areas caused by artificial light sources such as streetlights, buildings, and vehicles. This excess light scatters in the atmosphere, creating a luminous haze that diminishes the visibility of stars and planets. Skyglow affects natural nocturnal environments, disrupting wildlife, human health, and our ability to observe the universe. It is a form of light pollution that results from inefficient outdoor lighting and urban development, making the night sky less dark and less natural.
