Ultra‑Black Coating Proposed to Cut Satellite Light Pollution

Researchers have investigated a coating that absorbs nearly all visible light. The ultra‑black material is being considered for satellite surfaces. Applying the coating could reduce reflected sunlight that brightens the night sky. The study models the potential decrease in light pollution from orbit. Results show a notable improvement in preserving dark‑sky conditions. Astronomers welcome the prospect of mitigating satellite glare. Implementation would require testing durability in space environments. The findings could influence future satellite design standards.
