We are going to do a replay of the past with James Webb Telescope.Light that we see now has travelled billions of kilometres to reach Earth.It can be from other stars not just our star in our solar system,the sun.With the telescope in place we shall see how the universe was formed especially our solar system.So,when we do reflection of light using a telescope we are doing a replay of the past.
The telescope is made up of gold ( yellow mirrors below) because gold reflects light by 99%.
Don't miss the launch in December 22,2021.
