Tencent space news, according to foreign media reports. Recently, NASA engineers completed the integration of the James Webb Space Telescope giant gold lens and infrared observation channel test, and for the first time to uncover the mystery of the gold of the lens. When the telescope is assembled, the 18 reflecting mirrors which are composed of the main mirror are respectively covered by a black cover. Now, with the completion of the first piece of the main mirror assembly, these lenses have finally revealed the true face of Mount Lu. Greenbelt, MD., the United States of the NASA Goddard Space Flight Center stands the shiny gold mirror, the lens is by far the largest space telescope tablets, the engineers were still in the non-stop assembly test other lenses.

Scientists around the world by the unique telescope can not only observed galaxies formed in the early universe, 135 million years ago, and such as star forming nebula, extrasolar planet, even within our solar system of the moon and other celestial bodies in space radiation source can use the telescope to the full range of radiation. Made of beryllium lens can ensure its strength is hard enough and light weight, each lens has been cut into the size of the coffee table size, weighing about 20 kg. The mirror is covered with a thin layer of gold coating, in order to improve the infrared reflection degree.

Due to the complete assembled lens will than any a rocket fairing come more big, so on both sides of the lens is folded to reduce the volume. Each lens is equipped with a power device on the back to help the research team to control the movements of the telescope in space. The highly anticipated telescope will soon pass a series of rigorous tests to ensure that it will not be damaged during the launch. Within the next few months, engineers will assemble other major components, and additional various tests to ensure foolproof. The Webb James space telescope, the successor to the Harbert telescope, is the most powerful space telescope ever.

Webb telescope will be used to study the various stages of the universe, including the birth of the solar system, such as the earth can exist in the celestial stage of life, as well as the evolution of the solar system. The Webb telescope is expected in 2018 on the French Guiana boundary with Ariane 5 rocket launch. The project is led by NASA, the joint ESA (European Space Agency) and the Canadian Space Agency to complete the international cooperation project.
