This visualisation shows the progress of #reionization, an era when #Universe cooled down after the #BigBang, abt 13.8 B yrs ago.
Ionized regions are blue and translucent, ionization fronts are red and white, and neutral regions are dark and opaque.

In the #reionization era, #electrons & #protons combined to form neutral hydrogen gas.
This cool dark gas was the main constituent of #Universe during the so-called 'Dark Ages', when there were no luminous objects.

This phase ended when the first #stars formed & their intense ultraviolet #radiation slowly made the hydrogen fog transparent again by splitting the hydrogen #atoms back into electrons and protons.
This epoch lasted from abt 150 million to 800 million yrs after the #BigBang.
