A UK-based team plans to launch a satellite coated with Vantablack, the darkest material on Earth, to test if it can reduce light pollution from satellites and help preserve the night sky, addressing issues caused by the increasing number of spacecraft in low Earth orbit.
Surrey NanoSystems is testing a new Vantablack coating on a satellite to reduce light reflection from satellites like Starlink, aiming to mitigate their impact on ground-based astronomy, though satellite pollution involves other issues like radio interference and ozone depletion.
Artist Stuart Semple has developed Black 4.0, a new ultra black paint that absorbs an astonishing 99.95% of visible light, outperforming Vantablack. The paint creates visual effects by absorbing more light, making objects appear featureless and virtually disappear. Black 4.0 is more durable and stable than previous versions, with a new formulation and improved process. While not suitable for long-term outdoor use, it has applications in astronomy, photography, and creating ultra black backdrops. Black 4.0 can be brush painted and will be available in bulk containers.
