NASA Blueshift Follow. NASA Develops Super-Black Material That Absorbs Light Across Multiple Wavelength Bands. This close-up view (only about 0.03 inches wide) shows the internal structure of a carbon-nanotube coating that absorbs about 99 percent of the ultraviolet, visible, infrared, and far-infrared light that strikes it. A section of the coating, which was grown on smooth silicon, was purposely removed to show the tubes' vertical alignment. (Credit: Stephanie Getty, NASA Goddard). Flickr. CC BY 2.0.
