Based on the recent aeronautics reports, scientists find first Big Bang stars in brightest galaxy, thus contributing to the theories of universe formation. This galaxy contains light celestial bodies that determine the formation of other significant components in space.
A recent study conducted by researchers at the Institute of Astrophysics and Space Sciences proves that Big Bang galaxies still exist in the universe. Their declaration is grounded on the recent identification of the brightest distant galaxy, namely CR7.
The data on the new universe formation was collected with the help of a highly advanced telescope provided by the European Southern Observatory. The Very Large Telescope has helped scientists identify the components of the galaxy.
CR7 is made out of Population III stars, which are said to have lain at the core of the universe formation during the Big Bang explosion. These stars have a very short life, but they are the only ones that give birth to new categories of stars.
Population I and Population II stars are the most common and resistant in space. They are created by Population III stars and they contain heavy elements, such as, oxygen, hydrogen, carbon and iron. The only difference between the two categories of stars is that Population I stars are younger than the ones of the second category.
Unlike the aforementioned celestial bodies, stars belonging to the Population III category contain only light elements. In fact, the CR7 galaxy contains high emissions of ionized helium, which indicates that the majority of the stars in this island universe contain this gas.
Even though Population III stars live very little, they have an imposingly large size and they can be even brighter than the sun. As a consequence, the CR7 universe formation is one of the brightest in space.
The peculiarities of Population III stars are not the only aspects that scientists have taken into consideration when stating that the galaxy contain Big Bang elements.
They have also carried out tests with the help of the Very Large Telescope and found out that the same ionized stars were present 800 million years ago, short after the Big Bang took place.
Looking at the structure of these ionized stars is like looking back in history, scientists have concluded after publishing the findings of their study in the Astrophysical Journal.
The CR7 name of the brightest galaxy was inspired by the name of the popular Portuguese football player Cristiano Ronaldo. The leader of the study group, David Sobral, is from Portugal, as well, so he wanted his new scientific discovery to work as a reminder of the Portuguese national values.
