What is blacker than black? It's the super black paint known as Vantablack and its creator, Surrey NanoSystems, designed it to absorb 98 percent of light. BMW tested it out on one of its crossover model X6 cars just as an experiment in 2019. According to Space.com, the paint reflects only 2 percent of visible and infrared light.
Now AMSAT-UK is preparing to launch Vantablack on its Jovian-1 CubeSat mission to test its ability to avoid interference with space telescopes. The Jovian-1 goes into space sometime next year. Attendees at this year's AMSAT-UK Colloquium in October can expect to learn more about this adventure in light-pollution reduction.
Meanwhile if things work out, Vantablack might provide a solution for the private satellite constellations that researchers say have been interfering with ground-based astronomical research. As more satellites are being sent into space, that's not insignificant to observatories here on the ground.
