The World's Blackest Paint Could Stop Satellites Ruining Astronomers' Views
Researchers have developed a new application of Vantablack 310, the world's blackest paint, which could significantly reduce the brightness of satellites in low Earth orbit. Lab tests show that coating satellites with this material reflects only 2 percent of incoming light, making them much less visible to ground-based observatories. This could help mitigate the growing problem of satellite-induced light pollution, which is interfering with astronomical observations. The material's performance in simulations suggests it may be more effective than other satellite-darkening methods currently being tested.
Scientists tested a super-black paint called Vantablack 310 on satellites to reduce their reflectivity and help astronomers see the night sky better.
As more satellites are launched, they create light pollution that interferes with astronomical observations, and this paint could help minimize that problem.
This research shows how technological innovation can address unintended consequences of space exploration, benefiting both science and society.
