Scientists studying one of the earliest known galaxies using the James Webb Space Telescope have found that the universe's Era of Reionization may have occurred much earlier than previously thought.

Light from JADES-GS-z14-0 has taken 13.4 billion years to reach Earth, revealing a chemically mature galaxy when the universe was less than 300 million years old.

Scientists using the James Webb Space Telescope have identified an ancient and faraway galaxy that provides evidence that an important transition period that brought the early universe out of its "dark ages" occurred sooner than previously thought.
