[ 1 ][ 2 ] In a descriptive sense, the term light pollution refers to the effects of any poorly implemented lighting sources, during the day or night. Light pollution can be understood not only as a phenomenon resulting from a specific source or ...
Ecological light pollution [1] is the effect of artificial light on individual organisms and on the structure of ecosystems as a whole.. The effect that artificial light has upon organisms is highly variable, [2] and ranges from beneficial (e.g. increased ability for predator species to observe prey) to immediately fatal (e.g. moths that are attracted to incandescent lanterns and are killed by ...
Skyglow. Skyglow (or sky glow) is the diffuse luminance of the night sky, apart from discrete light sources such as the Moon and visible individual stars. It is a commonly noticed aspect of light pollution. While usually referring to luminance arising from artificial lighting, skyglow may also involve any scattered light seen at night ...
The dark-sky movement is a campaign to reduce light pollution.The advantages of reducing light pollution include an increased number of stars visible at night, reducing the effects of electric lighting on the environment, improving the well-being, [1] health [2] and safety [3] of people and wildlife, [4] and cutting down on energy usage.
Globe at Night is an international scientific research program that crowdsources measurements of light pollution in the night sky. At set time periods within each year, the project asks people to count the number of stars that they can see from their location and report it to the project's website. The coordinating researchers compile this ...
For those hoping to spot the aurora, meteorologists have advised staying away from areas with light pollution and using a long exposure camera as they are better able to adapt to different ...
Bortle scale. The Bortle dark-sky scale (usually referred to as simply the Bortle scale) is a nine-level numeric scale that measures the night sky 's brightness of a particular location. It quantifies the astronomical observability of celestial objects and the interference caused by light pollution.
Visual pollution refers to the degradation of the visual environment due to unattractive or disruptive elements that negatively impact the aesthetic quality of an area. It can affect urban, suburban, and natural landscapes. [1] It also refers to the impacts pollution has in impairing the quality of the landscape, formed from compounding sources ...
