Scientists measure all the stellar light created by the visible universe



After analyzing data from NASA's Fermi Gamma -Air Space Telescope, astrophysicist at Clemson University (South Carolina, USA), Marco Ajello and his team found that the universe generated 4 with 84 zero stellar photons.

This amount, according to scientists, is equivalent to 4.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000. 000 photons, that is, visible light particles.

Astrophysicists believe that our universe, about 13,700 million years ago, began to form the first stars when it was several hundred million years ago.

Now, according to his calculations, he has about two trillions of galaxies and trillion trillion stars.

"From the data collected from Fermi telescopes, we could measure the total amount of star being broadcasted, which has never been before," said Ajello, lead author of the study.

The scientist explained that most of this light was emitted by stars in the galaxies, enabling the team to "better understand the process of evolutionary star and gain a vision of how the universe produced its brilliant content."

Despite a tremendous number, Ajello said that "it is interesting to note that, apart from the light emanating from his own sun and the galaxy, the rest of the starlight reaching the Earth is extremely weak," an equivalent lamp of 60 W. Scientists measure all the stellar light that has created a visible universe

Washington, November 29 (EFE). – A team of American scientists has calculated all the stellar light that has been visible to the universe since its inception, according to a research published today by the specialized Science Journal.

After analyzing data from NASA's Fermi Gamma -Air Space Telescope, astrophysicist at Clemson University (South Carolina, USA), Marco Ajello and his team found that the universe generated 4 with 84 zero stellar photons.

This amount, according to scientists, is equivalent to 4.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000. 000 photons, that is, visible light particles.
