This humongous mirror will enable the telescope to take close-up shots of the universe and some galaxies that are 13.5 billion years old, according to NASA.
The mirror is composed of 18 hexagonal segments which are made of beryllium. Each one has a weight of 46 pounds. The gold coating is very thin. Gold reflects light that lies in the infrared part of the spectrum.
The total amount of gold employed in the coating equals a golf ball. It has been beaten thin till it is barely a non-existent veneer. This mirror can fold up to fit within a rocket.
The James Webb Space Telescope will be launched on its journey into space in 2018. It will be the most potent instrument of its kind. The layer of gold as mentioned before is microscopic.
