by For those of us who love to look up at the night sky and see how beautiful the universe is with all the bright little dots we call stars, what happens over the years is desperate. the phenomenon sky is decreasing more and more number of stars observed in the sky with the naked eye. Understand how this effect is caused.
The fading stars! i know why
Learn why we see fewer stars in our sky every day, and why this could become a big problem in the future.

This phenomenon is nothing more than the light pollution emitted mainly by big cities. However, over the years, this pollution increases more and more and this causes the “loss” of the stars. According to new research, this phenomenon, called skyit has stolen nearly a third of all humans from our galaxy’s sight.
The authors estimate that 80% of people in the US and 30% worldwide cannot observe the Milky Way’s etheric arc on a clear night.
According to Christopher Kyba, lead author of this new study, part of the problem with what we can see with the naked eye has to do with the types of lighting used.
More light in the sky, fewer stars
“LED lights have a strong effect on our perception of how bright the sky is,” Kyba said. “This may be one of the reasons behind the discrepancy between the satellite measurements and the sky conditions reported by the survey participants. globe at night.”
More developed countries are more affected, precisely because they have more large cities that emit an excessive amount of artificial light into the sky, and this problem is not only in our vision when we look at the sky. It mainly affects satellite observations and even nocturnal animals.
affected by light
In addition to the effects on astronomy, there are other consequences, especially on other animals. According to his manager globe at nightConstance Walker, Skyglow is beginning to affect diurnal and nocturnal animals, and this could lead to future problems in how these animals hunt and survive.
It also draws attention to the fact that there is little interest in dark sky conservation and that more studies are needed to report the consequences of this phenomenon.
“The increase in sky brightness over the past decade underscores the importance of redoubling our efforts and developing new strategies to protect the dark sky,” says Walker.
