How bright is the night sky above your home compared to truly dark wilderness areas? This is the question investigated by citizen scientists participating in the Globe at Night project. Rather than seeing simply “darkness,” trained observers recognize that night skies exist on a spectrum of brightness. By counting visible stars within specific constellations or measuring sky glow with specialized meters, participants quantify what was once just a subjective experience. These data help researchers track light pollution trends and their effects on wildlife and human health.
