"NASA's Webb Space Telescope Unveils Galaxies' Transformation of the Early Universe"

NASA's James Webb Space Telescope has provided new evidence on how galaxies transformed the early universe. The telescope observed galaxies that existed when the universe was only 900 million years old and found that the stars in these galaxies emitted enough light to heat and ionize the gas around them, creating transparent "bubbles." These bubbles eventually merged, leading to the clear and expansive views of the universe we see today. The findings shed light on the Era of Reionization and offer insights into the formation and evolution of galaxies in the early universe.
