Green Pea galaxies in the early dark universe

At a news conference in January astronomers using the James Webb Space Telescope stated they have spotted tiny galaxies that they understand could have been part of the greatest remodel in cosmic history called reionization. This was when most of the hydrogen atoms had their electronics ripped away in the very early universe.

In the immediate aftermath of the Big Bang the universe blindingly bright and hot, the heat so great that electrons were unable to join with protons to form atoms. The universe was a sea of plasma, dense gas of ionized particles. As the universe had cooled atoms started to form into the first stars and galaxies, but the surrounding dense gas absorbed their light create a cosmic dark age.

Green Pea Galaxies are named due to the colour and very small size; they are less than a 10th the size of the milky way with about 1 percent the mass. Green Pea Galaxies are very rare in our present day universe, but roughly 700 million years after the Big Bang these small galaxies maybe the route cause for the end of the dark universe.

Green Pea Galaxies although very small can produce stars at 100 times the speed expected due to the mass and contain very few heavy elements. Green Pea Galaxies leak more UV light than standard galaxies, it's this UV light that rips electronics from atoms.
