The James Webb Space Telescope (JWST) is the most powerful space telescope ever built, and it is capable of observing galaxies that are billions of years old. These galaxies are made up of primordial stars, which are the first stars that formed in the universe.

JWST is able to see these galaxies because it is equipped with a near-infrared camera (NIRCam). NIRCam is able to detect light that is emitted by the first stars, even though this light has been stretched to longer wavelengths by the expansion of the universe.

The light that JWST collects from these galaxies can tell us a lot about the early universe. For example, by studying the spectra of these galaxies, astronomers can learn about the composition of the first stars and the conditions under which they formed. JWST can also help us to understand how the first galaxies evolved into the galaxies that we see today.

JWST is a powerful tool that is helping us to learn more about the early universe. By studying the light from primordial galaxies, JWST is helping us to piece together the story of how the universe came to be.
