Webb Telescope sheds light on early universe transformation by galaxies.
TL;DR Summary
New observations from NASA's James Webb Space Telescope have provided evidence that galaxies that existed 900 million years after the big bang ionized the gas around them, causing it to become transparent. The galaxies' stars emitted enough light to heat and ionize the gas around them, clearing our collective view over hundreds of millions of years. These regions of transparent gas are gigantic compared to the galaxies, and over the next hundred million years, these transparent "bubbles" continued to grow larger and larger, eventually merging and causing the entire universe to become transparent.
