Green pea galaxies might have played a key role in the reionization process.
BEACON TRANSCRIPT – New data recorded by the Hubble telescope unveiled that green galaxies are pivotal in understanding the Universe. Researchers have their reasons to believe that the bright green galaxies are responsible for the great heating event, which took place 13 billion years ago.
The study containing the latest researcher on the small greenish galaxies has been published in the Journal Nature. These small and compact galaxies were discovered back in 2007 and many researchers believe that they are the main reason why the Universe reheated many years after the Big-Bang.
As the story of genesis unveils, it would seem that after several hundred thousand years after the Big Bang took place, our Universe became very compact. Subsequently, its internal temperature increased. This is the main reason behind the reionization of the matter.
The reionization process was lengthy. According to certain estimates, it would seem that the whole reionization stage spanned over 380.000 years. After the reionization of the matter was complete, the Universe’s began to cool down. The matter will begin to settle down via the neutralization process. In times, this leads to the formation of several gas clouds, containing high concentrations of helium and hydrogen.
According to the scientists, after the Universe cooled down and the matter began to settle, something unexpected happened. This unexpected event led to another heating stage, which took place roughly 13 billion years ago, the reheating event being one billion years apart from the Big Bang.
Astrophysicists have determined that green galaxies are pivotal in understanding the Universe. According to their recollection of the events, it would seem that the green pea celestial bodies have something to do with the great reheating event. But, as all theories regarding genesis, the subject is opened for debates.
But, there is yet hope for us. According to the team of scientists working on the project, over the years, Hubble managed to collect a heap load of data via its ultraviolet spectrometer. The space telescope was able to identify and study no less than five individual green pea galaxies.
The readings taken by Hubble indicate that these mysterious green galaxies are still emitting a high level of ionizing photons through the space between galaxies. The idea is still opened for debates, but the scientists have a hunch that these ionizing photons are the key to understating why the Universe began to reheat and what led to the second ionization period.
In conclusion, green galaxies are pivotal in understanding the Universe because scientists have a lot of reasons to believe that they are responsible for the second heating and reionization processes.
