'The eye' of the gold machine looks back past 13.5 billion years

Engineers at the US Aeronautics Agency (NASA) unveil the massive gilded mirror of James Webb space telescope during assembly and testing.

According to Phys.org, 18 mirror pieces make up the main mirror face protected by a black coating when fitted to the telescope structure. This is the first time the covers have been lifted since engineers completed the main mirror surface.

Standing up and radiating golden light inside the sterile room of NASA's Goddard Space Flight Center in Greenbelt, Maryland, USA, the mirror has the largest size of the mirrors into the universe and "child eye " of James Webb telescope as described by NASA. Currently, the engineering team is busy assembling and testing other telescope parts.

Scientists around the world will use this unique observatory to record the image and spectrum of the first galaxies that appeared in the early universe more than 13.5 billion years ago, along with all celestial bodies such as star-forming nebulae, extrasolar planets, their planets and satellites in the solar system. In order to ensure a durable and lightweight mirror surface, the engineers team made mirrors from beryllium materials.

Each mirror is as big as a water table and weighs about 20kg. The fully assembled mirror is larger than any type of rocket, so the sides of the mirror are folded. After each mirror piece there are control motors so that the engineering team can adjust the telescope's focus in the universe.

This waiting telescope will undergo rigorous tests to ensure it remains active when launched into space. Over the next few months, engineers will install other important equipment, and further adjust to make sure the glass is ready before the launch day.

The James Webb Space Telescope is the next version of Hubble glasses. The device will become the strongest telescope made by NASA. James Webb will study many stages in the history of the universe, including the formation of star systems that favor life on Earth-like planets, as well as the evolution of the solar system.

As expected, the glass will launch on Ariane 5 rocket in Guiana province, South America, 2018. James Webb telescope is an international project conducted by NASA in cooperation with the European Space Agency (ESA ) and Canadian Space Agency.
