Astronomers have discovered a "team" of ancient super bright galaxies that could explain the evolution of the universe.
Theories suggest that the universe was dark 150 million years after the Big Bang. It is consists of hydrogen and helium atoms before the first star was born.
The first generation of stars was said to be too powerful that they broke down the hydrogen atoms around them that paved the way for life to thrive. Looking at these super bright stars is like looking back on the ancient times according to the research team from the Lancaster University.
Researchers confirmed that they are now looking at bright stars that give them clues about the ancient time. Subaru and Keck telescopes in Hawaii were used by the team of astronomers for this study and the Very Large telescope in Chile, according to Astronomy Now. They have discovered galaxies that seem to have large bubbles of ionized gas, making it transparent to light.
"Stars and black holes in the earliest, brightest galaxies must have pumped out so much high energy/ultraviolet light that they quickly broke up hydrogen atoms. These galaxies are visible because large enough bubbles have been carved around them, but what is really surprising is how numerous these spectacular galaxies are," Dr. David Sobral, team lead said in an interview with Science Daily.
According to other astronomers involved, the study of the faint light sources from the early universe is not easy because they are much harder to detect. And finding such bright ancient stars means it'll give researchers tons of information that could potentially help them explain how the universe was formed.
Today, there are five bright sources confirmed and according to researchers and astronomers, there could be more of them waiting to be discovered. CR7 is the latest team of bright stars to be included on the roster.
Currently, the behavior, composition, size and shape of the ancient galaxies are being studied and observed by astronomers, and by looking back, they might be able to explain how life began in the universe.
