Everything is stardust, the scientists believe. Accordingly, right after the creation of the Universe upon the Big Bang explosion, the stars have been responsible for the occurrence of the heavy chemical elements which are the building blocks for the planets and life on Earth, also. Stars are also crucial for scientists, as they reveal many essential details on the history of the Universe. However, newly discovered giant stars might rewrite the history of the Universe.
According to astronomers, massive stars live for a shorter period, and then they explode as supernovae which can form new stars, black holes, and even new solar systems.
Nothing is vanishing in the Universe, as everything tends to transform into another form of “existence.”
In essence, knowing more about stars leads to a better understanding of the galaxies formation which, consequently, allows astronomers to shed more light on the history of the Universe and how did life develop.
Newly discovered giant stars might rewrite the history of the Universe
Recent observations made with the Atacama Large Millimeter/submillimeter Array telescope, known as ALMA Telescope, allowed scientists to notice that, in the Universe, there are stars more massive than science has ever theorized, as well as early galaxies way larger than scientists ever believed.
According to Fabian Schneider from the University of Oxford, the astronomers found around 30 percent more giant stars than they’ve ever expected. These stars present masses of about 30 times larger than our Sun’s mass.
Also, the scientists observed 70 percent more stars than they’ve ever imagined with masses of about 60 solar masses.
“Our results challenge the previously predicted 150 solar mass limit for the maximum birth mass of stars and even suggest that stars could have birth masses up to 300 solar masses!” concluded Fabian Schneider.
Thus, the discovery of these giant stars might rewrite the history of the Universe which was theorized, until now, based on models with smaller stars.
