Stars are “Disappearing from the Night Sky”, Astronomers Warn

Astronomers have warned that stars are disappearing from the night sky before our eyes. Skies are getting brighter by up to 10 percent each year, according to a major new study.

That means a large number of stars that were once visible are now hidden from astronomers and the general public. For example, a child born under 250 visible stars might only see 100 of them by their 18th birthday, the scientists warn.

And it could have drastic consequences, not only for nighttime sky visibility but also for the environment, affecting the biological systems of animals and humans, and more. born under 250 visible stars might only see 100 of them by their 18th birthday, the scientists warn.

The light pollution blocking these stars is growing much faster than we thought, even despite attempts to limit it. And it could have drastic consequences, not only for night sky visibility, but also for the environment, affecting the biological systems of animals and humans, and more.

She aimed to fully understand the magnitude of the problem of “sky glow,” or diffused light in the night sky caused by man-made pollution.

So far, changes in sky brightness have been poorly documented because there is no easy way to collect information globally. To counteract this, scientists used information from an app that collects and summarises views from around the world.
