Vantablack

British researchers have developed a new material that is so black it looks like a black hole. This  color, known as vantablack, absorbs all but 0.035% of light. It was created using carbon nanotubes, which is much thinner than human hair and so miniscule that light cannot get in but can pass into the gaps in between. The super black material has been developed for use in astronomical cameras, telescopes and infrared scanning systems. It reduces stray-light, improving the ability of sensitive telescopes to see the faintest stars. Its ultra-low reflectance improves the sensitivity of terrestrial, space and air-borne instrumentation. Here is a video explaining the material.
