A group of scientists is now reaping the fruit of their labor after discovering a very old and not-so-near-from-the-Earth galaxy after years of studying the universe. In an article published in A strophysical Journal Letters, Adi Zitrin, a NASA postdoctoral scholar in astronomy, and Richard Ellis, a recent retiree of CalTech, described the magnificence of what they now call as EGS8p7, a galaxy that is just 500 million years younger than the universe itself.

“The galaxy we have observed, EGS8p7, which is unusually luminous, may be powered by a population of unusually hot stars, and it may have special properties that enabled it to create a large bubble of ionized hydrogen much earlier than is possible for more typical galaxies at these times,” said Sirio Belli, a Caltech graduate student who worked on the project.

As most scientists said, the discovery could potentially change a big fraction of whatever has been thought of the universe in the past years especially theories written on its evolution, adding that “this kind of universe should not exist at all.”

“ The universe remains ionized today. Prior to reionization, however, clouds of neutral hydrogen atoms would have absorbed certain radiation emitted by young, newly forming galaxies, including the so-called Lyman-alpha line, the spectral signature of hot hydrogen gas that has been heated by ultraviolet emission from new stars, and a commonly used indicator of star formation. Because of this absorption, it should not, in theory, have been possible to observe a Lyman-alpha line from EGS8p7,” Mark Prigg explained.

Hence, the validation of this discovery from the rest of the scientific community could lead to a total rewriting of the universe’s history.

The calculation is made possible through redshift, a measurement of how long light takes to reach the Earth. According to Zitrin and Ellis, spectrographic analysis of the newly discovered galaxy has a redshift of 8.68. The previous most distant galaxy discovered has a redshift of 7.73.

“We are currently calculating more thoroughly the exact chances of finding this galaxy and seeing this emission from it, and to understand whether we need to revise the timeline of the reionization, which is one of the major key questions to answer in our understanding of the evolution of the universe," Zitrin said.

Although the discovery is obtaining attention from the world of astronomy today, many scientists are still waiting for more detailed explanations as the study remains far from over. Since it could “could cause a re-evaluation of ionization in the early universe, and us a better understanding of how humans are formed,” Zitrin and Ellis will still conduct further investigations on the subject.

The latest discovery by technology innovator Thunder Energies Corporation (OTCQB: TNRG ) , have also astounded the professional astronomy world after it announced that it has successfully detected antimatter particles through its new invention, the Santilli Telescope .

It was the first time in history that antimatter particles have been detected by the naked eye. Even modern greats—Einstein, Newton, Galileo, to name a few—have already described the particles as “difficult to detect,” if not “totally nonexistent at all.”

“The Santilli Telescope will pull back the curtain of the heavens, thus enabling amateur astronomers to photograph for the first time visual evidences of antimatter galaxies. Discovery has always been a motivating factor in amateur astronomy, and with the Santilli Telescope, discovery can happen,” Dr. Ruggero Maria Santilli, the brain behind the telescope, said in a statement.

Doubts, however, is an essential thing in the space exploration segment. In the past, this has encouraged many scientists and researchers to put more time and effort in what they do to either prove critics wrong or to abandon their early discoveries to pave the way for new, more revolutionary ones.
