A global honoring of the night sky sparks new conversations about light pollution, wildlife protection, and how cities can rethink the way we illuminate our world.

Did You Know? It’s International Dark Sky Week, a worldwide celebration dedicated to honoring the night — and a call to rethink how much artificial light we pour into our skies. The movement urges communities to reduce unnecessary lighting, cut pollution, and restore the natural darkness that wildlife and humans both depend on.

Across the globe, cities and local governments are stepping up. Some are dimming streetlights. Others are switching to warmer tones. Many are hosting awareness events to help residents understand why the night matters — and how over‑illumination disrupts ecosystems, migratory patterns, circadian rhythms, and even human health.
PBS NewsHour’s Malcolm Brabant, reporting from Denmark, digs into how European cities are experimenting with new lighting strategies. From red‑toned streetlights to motion‑sensitive illumination, these innovations aim to protect nocturnal species while still keeping communities safe.
It’s a reminder that the night sky isn’t just beautiful — it’s essential.
