The ministry is targeting protected astronomical zones after a proposed green energy project near the Paranal Observatory was canceled in January following global scientific opposition.
Experts warn that outdated laws leave the Atacama's world-class observatories vulnerable to future industrial threats, risking unique astronomical research and the upcoming $1.5 billion Extremely Large Telescope.
The Atacama Desert, with over 300 clear nights annually, is crucial for international astronomy, but ongoing urban and industrial expansion continues to threaten its exceptional conditions despite past lessons from similar environmental losses.
Could a similar battle between green energy and dark skies erupt in the American Southwest?
What search for new Earth-like planets was nearly blinded before it could even begin?
How is the fight to save the Atacama’s sky also a fight for our own health and ecosystems?
With one threat gone, what is the next danger looming over our clearest window to the universe?
Did Chile have to sacrifice a $10 billion green energy future to save the stars?
Chile’s Dark Skies at Risk: How the Dark Skies Council Stopped a 35% Light Pollution Surge from the INNA Mega-Project
Overview
In response to AES Andes' proposed INNA mega-project near Chile's key observatories, the Dark Skies Council formed in 2025 to oppose it, highlighting severe risks like a 35% increase in light pollution and other environmental harms. They argued existing regulations were insufficient and launched a public campaign that sparked widespread citizen involvement and national attention. This pressure, combined with technical evidence, led to the project's withdrawal in early 2026. Chile's 2023 Norma Luminica established strong lighting standards, but enforcement challenges remain. Grassroots groups like Fundación Cielos de Chile use innovative tools and local partnerships to bridge gaps, while ongoing advocacy pushes for permanent buffer zones to protect Chile’s irreplaceable dark skies amid growing development pressures.
