NASA Develops Super-Black Material That Absorbs Light Across Multiple Wavelength Bands
One thing bugs me a little though. (lack of specific knowledge in this area on my part no doubt.)
As its also highly absorbent in the far-infrared ... that kinda bags the question at what range in the EM spectrum it might actually radiating the absorbed light(energy) out again. If it matters that is. (No mention of any chemical processes here, so assuming there is none to speak of.)
Wonder if this might make it in the James Webb Space Telescope. ... Well, If the telescope itself will make it of course. Fingers crossed.

Carbon never stops to amaze me."NASA engineers have produced a material that absorbs on average more than 99 percent of the ultraviolet, visible, infrared, and far-infrared light that hits it -- a development that promises to open new frontiers in space technology. ..."

As I don't really see what the absorption level/behavior for visible light of a material has to do with its heat dissipation level/efficiency.The blacker the material, the more heat it radiates away.
