How does light pollution affect stargazing?

As light pollution increases, skyglow from unshielded lights make the night sky brighter and obscures the Milky Way from view. When astronomers try to look at faint or dim objects through optical telescopes, like galaxies, nebulae, or star clusters, the same thing happens, and they get washed out by skyglow.

What will happen if light pollution continues?

Too much light pollution has consequences: it washes out starlight in the night sky, interferes with astronomical research, disrupts ecosystems, has adverse health effects and wastes energy.

Do LED lights reduce light pollution?

Outdoor LED lighting now not only reduces light pollution but also saves users money and reduces energy. Initially, LED street lights reduced power consumption by 40 to 60 percent. After the lights were reengineered to reduce light pollution, energy savings jumped another 10 to 50 percent.

Where is light pollution the worst?

Light pollution in Hong Kong was declared the ‘worst on the planet’ in March 2013. In June 2016, it was estimated that one third of the world’s population could no longer see the Milky Way, including 80\% of Americans and 60\% of Europeans.

What is sky glow pollution and how does it affect astronomers?

Astronomers are particularly concerned with sky glow pollution as it reduces their ability to view celestial objects. More than 80 percent of the world’s population, and 99 percent of Americans and Europeans, live under sky glow. It sounds pretty, but sky glow caused by anthropogenic activities is one of the most pervasive forms of light pollution.
