The most recent exciting discovery comes from the new James Webb Telescope. This telescope can observe some of the first galaxies in existence!! That means we can observe galaxies that arose following the Big Bang. We also learned from this telescope that we should not call these galaxies “young” or “old” as we see them as they appeared when they were very young, perhaps even a striking hundred million years ago. Although we still require evidence to see the results of Webb’s mission, we can conclude that its technology has the miraculous ability to observe infrared light, which has taken 4.6 billion years to reach us. This information confirms the age and distance of galaxies. This light comes from the most distant galaxies as the universe’s expansion moves ultraviolet light into the infrared. As the universe itself is 13.8 billion years old, we can now see special objects that are distant and follow just a few hundred million years after the Big Bang occurred.
