Read our privacy policy Nasa has begun the process of focusing the James Webb Space Telescope so that it may capture images of stars and galaxies shortly after the Big Bang. The alignment will take an additional three months, Lee Feinberg, the Webb optical telescope element manager at Goddard, told Reuters by telephone. The telescope’s smaller, secondary mirror, designed to direct light collected from the primary lens into Webb’s camera and other instruments, must also be aligned to operate as part of a cohesive optical system. The efficiency of the Webb launch also means the telescope is expected to run for 20 years, rather than the decade Nasa predicted, giving scientists a longer time to study the origins of our universe.
