Surrey team tests black paint to combat satellite light pollution

Researchers explore new paint to prevent interference with night sky observations.

Surrey scientists test black paint to reduce satellite light pollution

Scientists at the University of Surrey are experimenting with a unique paint designed to reduce light pollution from satellites. Noelia Noel, an astrophysicist, leads the effort with Vantablack 310. This specially developed paint could be applied to satellites, potentially minimizing their visibility from Earth. The objective is to protect ground-based telescopes that suffer from light interference, disrupting astronomical observations. This is particularly relevant for observatories such as the Vera C Rubin Observatory in Chile, where satellite reflections compromise image quality.

The initiative by Surrey scientists highlights a growing concern in the astronomical community about the increasing number of satellites in low Earth orbit. As companies like SpaceX launch thousands of satellites, traditional observation methods face significant challenges. Implementing solutions like Vantablack 310 could represent a crucial step toward sustainable space practices, allowing for clear night skies while accommodating advancing space technology.
