GLOBE at Night

🌙✨ How dark is your night sky? This March, join the global @GlobeatNight campaign and help measure light pollution around the world. 🌍 It only takes a few minutes, but your observation can make a real difference! Get started: globatnight.org

@GlobeatNight turns 20 years! 🌌🎉 And what better gift than a short video showing your love for dark skies? To celebrate, we’re inviting you to send us a short video sharing why dark skies matter to you 🌍✨ 🎥 How to participate: globeatnight.org/love-your-star…

More light does not always mean more safety. Excessively bright bulbs often reduce visibility by creating glare and shadows. Lower-wattage bulbs aimed properly can improve visibility while saving money and protecting the night sky. #DarkSkyTexas #ResponsibleLighting

Light pollution doesn’t stop at the street. It disrupts wildlife, ecosystems, and even pets at home. Artificial light at night throws off hormones, stress levels, and behavior. Protect the night. Protect life. #DarkSkyTexas #WildlifeProtection #LightAwareness

Just another reason to protect our dark skies… looking at glowworms! Glowworms, and many other nocturnal species, rely on Earth’s daily day and night cycle to govern their life-sustaining behaviors. 🌅➕🌌🟰🙂 More at 🔗GlobeatNight.org 📷KPNO/NOIRLab/NSF/AURA/R. Sparks

Have you ever seen a truly dark night sky? 🌌 If not, you’re not alone. 80% of the world lives under a sky polluted by artificial light. Fortunately, light pollution can be controlled by shielding lights to limit the area where they shine💡 📷 @GeminiObs/NOIRLab/AURA/Kwon o chul
