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.

The space telescope's image of a odd-looking spiral galaxy is, in reality, two distant galaxies overlapping each other.

Astronomers have identified a bright hydrogen emission from a galaxy in the very early universe. The surprise finding is challenging researchers to explain how this light could have pierced the thick fog of neutral hydrogen that filled space at that time.
