NASA's James Webb Space Telescope detected three early-universe galaxies, 400-600 million years post-Big Bang, providing insights into galaxy and star formation.

NASA's James Webb Space Telescope has detected three galaxies from the early universe, around 400-600 million years after the Big Bang. The galaxies, which existed 13.3-13.4 billion years ago, are surrounded by gas rich in hydrogen and helium, the first elements in the cosmos. These findings offer valuable insights into the early formation of galaxies and stars.
