There is a big gap in our observations from the CMB to the first galaxies almost a billion years later. The James Webb Space Telescope will help close that gap by looking for the first stars in the infrared.

The first stars were initially very bright in the ultra-violet, and after 12 billion or so years, that light has been redshifted to the IR.
