If you’ve ever driven around a city at night, you know lights are everywhere, pointed haphazardly, and are at times blinding to look at. It is also clearly noticeable how few stars are visible in larger cities. This issue is more than just invisible stars and squinting while driving.
Astronomical observations are important for growing the human wealth of knowledge, watching for potential dangers, and gathering a better understanding of our planet. Light pollution can be a serious hindrance to the advanced telescopes that make critical observations and are extremely sensitive to the smallest amount of light. Small changes like covers on the top of lights to aim them down are simple, effective, and help with the light shining into your bedroom at night. Keep our skies dark, for you and the stars.
