What the Webb Space Telescope Will Show Us Next
When the Hubble Space Telescope launched, we soon learned its images were blurry. Engineers had to build the equivalent of eyeglasses for it. Were there any such problems with J.W.S.T. early on, given its very complicated deployment?
Because of the way it worked, when Hubble went up in space, the optics had to be perfect. For J.W.S.T., we launched mirrors that were able to fix themselves. There are eighteen primary mirror segments—those beautiful gold hexagons—and the idea is that you
The James Webb Space Telescope Wants to See It All

The Big Bang had electrified the cosmos into existence, and the new landscape buzzed with particles, chaotic and hot, before cooling off into a calm expanse of hydrogen and helium. Then something began to happen in the fog. Gravity drove pockets of gas to collapse in on themselves and ignite, creating the first stars. The radiant orbs began to cluster, forming the first galaxies: messy, misshapen things, not as polished as
