VLBA image of the quasar P352-15 at a distance of nearly 13 billion light-years of the earth. Three main components of the object are visible, two of them showing an additional substructure.
You will need more than sunglasses to view this shiny object in the sky.
The most brilliant object in the universe was discovered, a quasar whose universe accounted for only 7% of its current age. ] The quasar, now known as PSO J352.4034-15.3373 (P352-15 for short), was discovered 13 billion light-years from Earth by the Very Long Baseline Array (VLBA) radio telescope
"We see P352-15 as it was when the Universe was less than a billion years old, or only about 7 percent of its current age," said Chris Carilli, of the National Observatory of Radioastronomy (NRAO) in a statement.
"It's near the end of a period when the first stars and galaxies re-ionized the neutral hydrogen atoms that invaded the intergalactic space."

Carilli adds: "Other observations may allow us to use this quasar as" background "lamp to measure the amount of neutral hydrogen remaining at that time."
Quasars are defined as extremely bright The active galactic core, powered by a black hole that is a billion times more massive than the Sun, according to Space.com
The light and radio emissions seen from the quasar are actually caused by the material around the black hole itself, known as an accretion disk. According to ScienceAlert, the disk eventually reaches a huge space, attracting dust and gas, so that it looks like water flowing into a drain.
The results of the research were published in The Astrophysical Journal on July 9th. Banados, from the Carnegie Institution for Science in Pasadena, California, noted that there is a "shortage of powerful radio transmitters known from the early days of the universe", making this discovery so important.

The quasar finally split into three distinct parts, the VLBA found – and researchers are trying to understand why.
They have two theories up to now.
The first explanation is that the images that researchers see are the bright core of the quasar itself, "corresponding to the location of the supermassive black hole itself, at one end, and the other two bright spots. are parts of a unilateral throw. "

" This quasar is perhaps the most distant object in which one could measure the speed of such a jet, "says Emmanuel Momjian, of NRAO.
The explanation is that the intermediate object is actually the nucleus and the other objects are ejected jets going in opposite directions.
More research is needed to determine which scenario is true, although the first explanation is most likely. , P352-15 offers researchers a lot to learn about the history of the universe, how it was formed and how it evolves.
"The brightness of this quasar and its great distance make it a unique tool for studying the conditions and processes that prevailed in the first galaxies of the Universe," said Carilli. "We can not wait to discover more of its mysteries."
