The James Webb Space Telescope: A Vision for the Future
... Longer wavelengths of light, such as infrared, result in lower-resolution images. To improve image sharpness, astronomers need a large mirror to collect a lot of light. The bigger the mirror, the more light it can collect. Webb will be able to see back to a few hundred million years after the Big Ba ...
