Dark and Quiet Skies Act of 2025

This bill establishes a voluntary "Center of Excellence for Dark and Quiet Skies" to help protect astronomical research from interference caused by satellites. The Center, funded with $20 million over five years, will work with satellite operators, observatories, and scientists to develop and share best practices for reducing optical and radio interference. It requires collaboration to create consistent measurement standards, test mitigation techniques, and publish research findings. The Center must engage diverse stakeholders, including Native entities and small businesses, and report annually to Congress on its progress.
