Vantablack: World's Blackest Paint Could Solve A Major Problem For Astronomy
Reported byScienceAlert ↗·Sourced by Goodlede
Lab testing by University of Surrey researchers shows Vantablack 310 coating on satellites reflects only 2 percent of incoming light, achieving magnitude 6.7–7.8 brightness—below the International Astronomical Union's magnitude-7 threshold and significantly better than uncoated SpaceX satellites (magnitude 3.7)—potentially mitigating satellite-induced light pollution affecting astronomical observations.
Performance has been demonstrated in lab and physics models; real-world durability and effectiveness in space remain to be tested.
