Every light alters their night.

For World Reef Day, we’re highlighting a growing but often overlooked threat to marine ecosystems: artificial light at night.

Research shows that 22% of the world’s coastal waters are exposed to light pollution, disrupting the natural darkness many marine species depend on to survive. Coral reefs rely on lunar cycles to synchronize spawning. Sea turtle hatchlings use darkness to find the sea. Zooplankton rely on darkness to safely migrate toward the surface at night. Even seabirds, crabs, and jellyfish can be affected by artificial light.

Blue-rich LEDs are especially concerning because their light penetrates deep into the water column, altering natural behaviors and biological rhythms below the surface.

Protecting the night means protecting oceans, reefs, wildlife, and the natural rhythms of life on Earth. Learn more: https://bit.ly/43TuyJL

This week’s from Pablo Fuentes captures a memorable night beneath the stars at the Tropic of Capricorn near San Pedro de Atacama. Taken during one of his first astrophotography outings on the high plateau, the image reveals subtle airglow, a meteor streaking overhead, and the kind of wonder that only emerges when we spend time under naturally dark skies.

From desert landscapes and mountain trails to quiet backroads and late-night conversations beneath the Milky Way, the night is full of endless adventures waiting to be experienced.

Not to make light of a devastatingly bright situation... but imagine a future where mirrors mounted to satellites in space beam sunlight back down to Earth at night, the night itself slowly being sold away to increase illuminated hours.

This is exactly what the startup Reflect Orbital has proposed.

DarkSky is urging the company and its investors to conduct a full environmental review before anything launches. Sign our open letter before it closes at the end of May: https://bit.ly/3KVsuvu

What if satellites outnumbered the stars? This is a reality we could be heading toward.

In a new article by DarkSky’s Executive Director and CEO, we explore the rapidly growing space economy, the challenges it presents, and the solutions we can implement to help keep our window to the universe open, recognizing dark, star-filled skies as a fundamental human right. https://bit.ly/4dqk3DR

This week marks seven years since the first launch of Starlink. In a new article, DarkSky’s CEO and Executive Director, Ruskin Hartley, warns that seven years into the era of commercial megaconstellations, we have arrived at a crossroad.

We can no longer just be passive critics standing on the sidelines wishing the satellites would go away. To protect our atmosphere, ensure civilian safety, and defend the visibility of the sky itself, we need a seat at the table to shape regulatory guardrails. It is time for international space law to recognize that a dark, star-filled sky is a fundamental human right.
