A research group from institutions in Germany and the United States analyzed over 50,000 observations from citizen scientists around the world from 2011 to 2022. The Globe at Night citizen science project has been up and running since 2006 and uses naked eye observations, or those without a telescope, and shows the important role that citizen science data can play in supplementing satellite measurements. Long after sunset, an artificial twilight glows in many spots around the world and this skyglow is a form of light pollution. Not only does it hurt stargazing and astronomy, but the extra light can affect animals’ sense of daily and seasonal cycles.
“Skyglow affects both diurnal and nocturnal animals and also destroys an important part of our cultural heritage,” says Constance Walker, a co-author and head of the Globe at Night project from the National Science Foundation’s NOIRLab, in a statement.

Interesting information Lt Col Charlie Brown. I somehow think this will get worse, not better. Especially since there was the big push for everyone to go LED.

One of my few fond memories of Vietnam, is the sky at night; sunsets and the stars. Just amazing! I moved out to the country and used ot enjoy the stars at night ... then a wonderful couple built near me. She likes light, and they had a streetlight put in the corner of their yard, close to my property and that diminished the stars visible. Then, another family built across the valley and put up a super bright, LED type of yard light and it's killed the view of the stars. Fortunately, their outstanding neighbors which offsets the disappointment of seeing the stars as well as when we first moved here.

Cool. But the more green we become the sky glow may be reduced. As pertaining to scarcity of energy to run lights , homes, cars, stadiums, cities in general.
