Scientists Discover the Oldest and Maximum Light-Giving Galaxy in the Cosmos Which, 13 Billion Years Away - A Quasar from a Time when our Universe was Just 7% of its Current Age.

It seems that scientists have found the oldest and maximum light-giving galaxy in our universe. Yet it existed so long ago in the past that they are not sure whether it still exists or not. The brilliant light reaching the astronomers’ telescopes may just be the afterlife remains or a ghost of this early galaxy.

For the team of dedicated scientists, this discovery was a pleasant surprise. It was through a radio telescope that the galaxy was detected. It seemed to be in the process of having released a jet of bright luminous particles.

The study got published in two papers in The Astrophysical Journal and it shows how our universe made the shift from its early youthful state to a more mature phase.

Quasars are basically composed of big black holes which exist at the centers of galaxies. This newly found one not only sucks up matter and light but also spews it out with great force.

Some of this matter which is ejected travels at lightning speed. The brightness is due to the volley of plasma that is sent forth from the quasar. This oldest and maximum-light giving galaxy is a finding which has the scientists amazed and amused.

Even though most quasars were discovered a half a century ago, only 10% of them give out such strong levels of radiation. One of the researchers spoke of how “It was the most detailed image yet of such a bright galaxy at this great distance.”

Of the universe’s total lifespan of 13.7 billion years, the light from this quasar has traveled some 13 billion odd years to reach us, earthlings. Thus it is very old. Such a discovery is rare indeed.

Not many such quasars exist in the depths of the cold and lifeless universe that we belong to. Since the Big Bang when the universe was a superhot soup of plasma, expansion has been the norm.

The discovery of this oldest and brightest ever galaxy will shed further light on how the youth of the universe was like.
