Light pollution is increasing, notwithstanding the countermeasures purportedly put in operation to limit it.""Twinkle, Twinkle, Little Star," could eventually become less of a lullaby and more of an elegy.
And as the sky gets brighter due to light pollution, it washes out the much fainter light of stars light years away. Of course, light pollution is nothing new, but whatalarming is that it's brightening the sky at a faster rate — "exponentially," the researchers say — than anyone expected. And that means stars are fading away.
Gauging the brightness of the sky, and by extension the overall visibility of stars, is surprisingly difficult. For one, satellites, including those used in previous studies of this nature, are not able to detect some of the blue light from LEDs, and in general, a satellite's perspective is drastically different than that of a human on the ground.
