The Number of Stars Visible To The Naked Eye is Decreasing Due to Light Pollution

Scientists have revealed that the number of stars visible to the naked eye in the sky has decreased significantly due to increased light pollution.

According to the BBC’s report, the data obtained by amateur astronomers by counting the stars in the sky that they can see with the naked eye for 12 years were recorded with the online project called “Earth at Night”.

The data showed that sky glow caused by the reflection of artificial sources into the sky has increased by 10 percent each year since 2021.

of the German Geosciences Research Center in Potsdam, who contributed to the study. Christopher Kyba said that star vision is gradually disappearing due to increased light pollution.

It has been noted that this increase in pollution means that the number of stars that a child born in a place where 250 stars can be seen will be born in the same region after 18 years will drop below 100.

Hoping that the steps taken in the field of energy saving in some urban centers in recent years will reduce light pollution, Kyba noted that different types of light sources worsen the brightness of the sky and said, “Remember that light pollution is wasted energy. “We continue to release this light energy into the atmosphere, and maybe that’s not what we should be doing.”


Light pollution experts Salvador Bara and Fabio Falchi, in their opinion article published in addition to the research, said that people admired the night images and videos of the planet released by the International Space Station (ISS), but they did not see it as an “evil”. light pollution picture”.

Experts described people’s finding these pictures beautiful as “attributing rainbow beauty to colored reflections in water due to chemical pollution.”

It has been reported that light pollution not only reduces star vision, but also harms human health by affecting sleep patterns, but also negatively affects animal behavior.

The study by Kyba and his team was published in the journal Science.
