James Webb Telescope Sees 'Birth' of Three of the Universe's Earliest Galaxies in World-First Observations
In an astounding breakthrough, the James Webb Space Telescope (JWST) has captured the birth of some of the universe's earliest galaxies. This unprecedented observation marks the first time astronomers have witnessed such early galactic formation. The Discovery A new study published in Science reveals that JWST detected three infant galaxies forming from a primordial cloud of hydrogen and helium gas just 400 to 600 million years after the Big Bang. This period is known as the era of reionization, a crucial phase when the earliest stars and galaxies began to shine through dense gas clouds, leading to the transparent universe we know today. "These galaxies are like sparkling islands in a sea of otherwise neutral, opaque gas," said Kasper Heintz, lead author and assistant professor of astrophysics at the Cosmic Dawn Center (DAWN), University of Copenhagen. "Without Webb, we would not be able to observe these very early galaxies, let alone learn so much about their form...
