Urban skyglow is the brightening of the night sky in metropolitan areas due to excessive artificial light, significantly hampering the visibility of stars and celestial bodies. This form of light pollution can have ecological impacts, disrupt human circadian rhythms, and obscure astronomical observations.

Celestial bodies are natural physical entities found in the universe, including stars, planets, moons, asteroids, comets, and meteoroids. They are studied to understand the formation, structure, and evolution of the universe, as well as the potential for life beyond Earth.

Light pollution refers to the excessive or misdirected artificial light that disrupts ecosystems, obscures the night sky, and can have adverse effects on human health. It is a growing environmental concern that affects astronomical research, wildlife behavior, and energy consumption patterns worldwide.

Light Pollution

Ecological impacts refer to the effects of human activities or natural events on ecosystems, including changes in biodiversity, ecosystem services, and habitat integrity. Understanding these impacts is crucial for sustainable development and conservation efforts, as they influence the resilience and functionality of ecological systems.

Ecological Impacts

Human circadian rhythms are internal biological processes that follow a roughly 24-hour cycle, influencing sleep-wake patterns, hormone release, and other vital bodily functions. These rhythms are regulated by the suprachiasmatic nucleus in the hypothalamus and can be affected by external cues like light and temperature, impacting health and well-being when disrupted.

Human Circadian Rhythms

Astronomical observations involve the collection and analysis of data from celestial objects and phenomena using telescopes and other instruments. These observations help scientists understand the universe's structure, composition, and evolution by studying light, electromagnetic radiation, and other signals from space.
