Abstract

Faraway galaxies are hard to detect, not only because they appear fainter, but also because the light that we detect from them is infrared. Many of these objects were invisible to us until the James Webb Space Telescope was launched. With this new telescope, scientists discovered 33 new galaxies in the early universe. This opens the door for James Webb to find many new galaxies.
