Stars are affected by pollution, may stop appearing in 20 years

Seeing stars in the sky brings comfort to many people. However, this sight may stop appearing in the next 20 years. Scientists have warned that the ability of humans to see stars in the night sky could end in the next 20 years due to light pollution. The situation of light pollution has worsened in the last few years.

In an interview with The Guardian, British astronomer Martin Rees told The Guardian that in 2016, astronomers reported that about one-third of people in the world no longer have the ability to see the Milky Way or the Milky Way. He said that due to LED and other types of lighting, the night sky is shining brightly. According to Martin, “The night sky is part of our environment and it would be a great loss if the next generation could never see it. It’s like if they never saw a bird’s nest. It’s your responsibility to care.” You don’t have to be an astronomer.”

Christopher Kyba of the German Center for Geosciences told that if a child is born in a place where 250 stars are visible at night, then only 100 stars will be visible when he is 18 years old. He said, “Until a few decades ago, people could see the night sky clearly. However, this sight has now become a rarity. Only a few of the richest or poorest of the world can see it and for the rest It’s almost over.” Kayba said that the situation can be improved a lot by making some changes in the lighting. These include turning down outdoor lights, limiting the brightness of the lights, and keeping the red and orange components of the lights blue and white.

In this regard, Professor Robert Fosbury at Britain’s Institute of Ophthalmology said that there is no red or infra red light in the blue emission from LEDs and this is reducing red and infra red light. This can have serious consequences. “When red light shines on our body, it reduces the high level of sugar in the blood and increases the production of melatonin. This may also be one of the reasons for the increase in diabetes and obesity,” he said.
