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.

Whare are the two galaxies in this Einstein ring? The elliptical galaxy at the center of this Einstein ring belongs to a galaxy cluster named SMACSJ0028.2-7537. It can be seen as the oval-shaped, featurless glow around the small bright core.

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.
