Vantablack is currently the world’s blackest substance – made of carbon nanotubes – absorbing a maximum of 99.965% of radiation in the visible spectrum. It’s comprised of a forest of vertical tubes which are “grown”, which when light strikes, instead of bouncing off, it becomes trapped and is continually deflected between the tubes before eventually becoming heat.

This substance has many potential applications, including preventing stray light from entering telescopes, and improving the performance of infrared cameras both on Earth and in space. Vantablack may also increase the absorption of heat in materials used in concentrated solar power technology, as well as military applications such as thermal camouflage.
