Observing the oldest Wolf disc at a distance of 12.3 billion light years


The oldest galactic “Wolf Disk” spotted 12.3 billion light-years, light was seen from the galaxy that had been traveling for 12.3 billion years at a speed of 3 km per second through the Atacama Large Millimeter telescope.

Astronomers have found the oldest and most distant galaxy to tend to challenge the current theory of how galaxies are formed during the early universe, and until now studies have shown that these huge systems consisting of stars, gases, and dust took shape slowly and steadily over billions of years, because the galaxy evolved at the beginning of the universe Through a violent operation.

However, it has been shown that the “DLA0817g” galaxy was found

A recently called Wolfe Disk took the shape of a disk at an early stage, although the universe is 13.8 billion years old, but galaxies did not form shortly after that.

The current shape is the result of a slow and steady change, and the scientists mentioned that there was a lot of collision and fusion that participated in the formation of galaxies, which is why they were given an irregular structure, and galaxies only began to form as a well-formed disk after only about 6 billion years of formation of the universe.

Light was seen from the Wolfe Disk galaxy, which had been traveling for 12.3 billion years at a speed of 3 kilometers / second, through the Atacama Large Millimeter telescope that showed the galaxy light 1.5 billion years after the Big Bang.

Astronomers have observed and confirmed that the Wolf disc galaxy took the shape of the rotating disk galaxy when the universe was only ten percent of its current age. The Wolfe disk is now rotating at 272 km per second.

A report of the National Radio Astronomy Observatory quoted Marcel Nillman of the Max Planck Institute for Astronomy in Heidelberg, Germany, who said that while previous studies indicated the existence of these early galaxies rich in rotary gas, thanks to ALMA we now have unambiguous evidence that they occur at a time Early 1.5 billion years after the Big Bang.
