In childhood, when we used to sleep on the roof and look at the sky at night, we used to see only stars everywhere. But now it is not so. If you live in any big city of India and want to see the stars at night, then it is almost impossible.
Especially for the people living in Delhi NCR, the stars are now disappearing. Even in villages, stars are not visible at night like before. In such a situation, the question arises that where are these stars going. Will we not be able to see even a single star in the sky in the future? Let us know about this in detail today.
why are the stars disappearing
If you think that the stars are going away from the sky, then you are wrong. The stars are still where they were hundreds of years ago. Actually, all this is happening because of light pollution. This is the reason why we cannot see stars in the sky at night.
Let us tell you, light pollution is the light produced by humans which illuminates the sky at night and hides the light of the stars. In fact, due to urbanization and industrial development, light pollution has increased rapidly in big cities around the world. This is why stars are not visible in big cities today. According to reports, about 80% of the world’s population lives in places where it has become difficult to see the stars clearly in the sky.

How dangerous is light pollution?
Scientists believe that if light pollution continues to increase at this rate, then in the future we may not be able to see stars with naked eyes from the earth. Due to light pollution, not only are stars less visible, but space research and astronomical studies are also getting affected. According to scientists, if light pollution continues to increase in this way, then in the future many astronomical events, such as meteor showers, sighting of planets and clear visibility of the galaxy, will almost come to an end.
Even NASA is surprised
Artificial light emitted from urban areas has increased rapidly in recent years, according to data from NASA’s Suomi National Polar-orbiting Partnership (NPP) satellite. This light, often coming from street lights and buildings, produces an effect called “skyglow.” It causes the night sky to become so bright that naturally shining stars and other celestial objects are not visible to us.
