Summary
Researchers at Surrey have demonstrated how Vantablack® 310, an ultra-black coating, could reduce satellite brightness and mitigate light pollution from spacecraft. The proliferation of satellites is creating bright streaks and flares that interfere with astronomical observations. The team measured the coating's light reflection under various conditions and simulated how coated satellites would appear less bright, potentially helping protect the night sky for both scientists and stargazers.

· 3 pulledThe proliferation of satellites already in orbit is raising concerns among scientists and stargazers.
Reflected sunlight from spacecraft can create bright streaks and flares that interfere with telescope observations and large-scale surveys of the night sky.
The research team measured how Vantablack® 310 reflects light under a range of illumination and viewing conditions.
