Recipe for the Perfect James Webb Space Telescope Mirror
Mirrors are a critical part of any space telescope, and the James Webb Space Telescope's mirrors are made of a special element that will enable it to withstand the rigors of space and see farther back in time/distance than any other telescope now in operation. Space telescope mirrors must endure the extremely frigid temperatures in space, be highly reflective, lightweight and tough. Those are exactly the qualities that make up the 18 mirrors being developed for the Webb Telescope.
