Lately, scientists have found the most distant galaxy known, named EGSY8p7. It is located around 13.2 billion light years away. Scientists said that the light from the universe must have started when the universe was in infant in cosmic time.

NASA's Hubble and Spitzer Space Telescopes spotted the galaxy. The data from the telescopes provided a hint to scientists that the galaxy was filled with unusually hot stars. With the help of the 10-meter Keck telescope in Hawaii, the researchers have detected the galaxy through ultraviolet light coming from its stars.

Astronomer Richard Ellis at the California Institute of Technology said that they found the light coming from the young, massive, hydrogen burning stars to be a surprise. It has been because the galaxy's distance acts as a throwback into a time during which cosmos was filled with clouds of neutral hydrogen.

Astronomer AdiZitrin, lead author of the paper, said that the galaxies like this one will provide new information about how re-ionization lifted the cosmos out of its dark age that lasted for around 400 million years after the universe cooled following the Big Bang.

As per the researchers, the re-ionization process would be 'very lumpy, so that we happen to see an object in a more re-ionized line of sight'. The researchers said that the general environment would have been foggy, but the object itself was quite energetic that it formed a bubble of re-ionized gas around it.
