New data shows light pollution has made the night sky today twice as bright as it was eight years ago. That would mean 60% of the stars we see today will be gone by 2041 if light pollution keeps growing. For decades, astronomers have been building telescopes in the darkest places on Earth to avoid light pollution. However, satellites miss the blue light of LEDs, which are commonly used for outdoor lighting – resulting in an underestimate of light pollution. Note: If a night sky containing 250 stars today has only 100 stars in 18 years, that equates to a loss of 60% of the stars in the night sky by the year 2041.
