NASA's Fermi Gamma-ray Space Telescope has provided data that has been used to measure all the stars that our universe has produced over 90 percent of its history, a space agency has shown. Scientists working on the project looked at gamma ray outputs from distant galaxies to measure star formation rates. This is the first time scientists have measured all the light of the stars that have been created in the history of the observable universe.
The research is based on the University of Clemson University, where astrophysicist Marco Ajello and postdoctoral scientist Vaidehi Paliya worked with colleagues on Fermi's telescope analysis. The work dealt with the history of star formation, which covered 90 percent of the history of the universe, and found that the stars were sending 4 × 10 ^ 84 visible light particles that produced the light of the stars.
Speaking of research, Ajello said:
From the data collected by the Fermi telescope, we were able to measure the whole number of stars that were ever published. It has never happened before. Most of this light radiates stars that live in galaxies. And so it allowed us to better understand the process of stellar development and gain a fascinating insight into how the universe produces its light content.
Despite the huge photon number, Earth still gains most of its light from the Sun due to the vast size of the universe. Starlight, which reaches the Earth from our galaxy, is as deep as a 60-watt light that can be seen more than two miles away and leaves us with a dark night sky, and in the distance visible small, bright stars.
NASA in the video explains how Fermi works and why his data is able to help researchers analyze the light of the stars of the universe. In addition to research in the inter-war survey, the study also independently confirms the estimates of past space-based creations based on deep mapping missions of galaxies.
The findings will help to improve future research on stellar evolution.
