Black

Actually I was going to introduce the big big news about the discovery of new type of life. from NASA. However Mr.KOUEI have already written the topic. So I will write other topic news from NASA and please read Mr.KOUEI's blog too. The article I paid attention is about the development of the matter blacker than black. This is very interesting too.

Black is black, right? Not so, according to a team of NASA engineers now developing a blacker-than pitch material that will help scientists gather hard-to-obtain scientific measurements or observe currently unseen astronomical objects, like Earth-sized planets in orbit around other stars.

The nanotech-based material now being developed by a team of 10 technologists at the NASA Goddard Space Flight Center in Greenbelt, Md., is a thin coating of multi-walled carbon nanotubes — tiny hollow tubes made of pure carbon about 10,000 times thinner than a strand of human hair. Nanotubes have a multitude of potential uses, particularly in electronics and advanced materials due to their unique electrical properties and extraordinary strength. But in this application, NASA is interested in using the technology to help suppress errant light that has a funny way of ricocheting off instrument components and contaminating measurements.

The black improved by the carbon nanotubes will be use to many kinds of study. For example, We can get to measure smaller lights from the universe. Now the current telescope use black paint to reduce the reflection of lights, but it is not perfect. The carbon nanotubes will make the black paint 10 times darker than it is. So it enables us to see the materials that we have seen as black.
