Recently, astronomers discovered a massive galaxy that was created just 1.5 billion years after the Bing Bang, questioning the accepted hypotheses of ‘how all the galaxies in the universe could develop.’
According to a report published in the journal Nature, after late astronomer Arthur M. Wolfe, the 12.5 billion-year – old revolving galactic disc has been dubbed “Wolfe Disk” galaxy DLA0817 g.
As the name suggests, ‘disk galaxies’ are disk-shaped star-systems, earlier observations showed these types of galaxies gradually formed, and only much later did they reach a large mass.
Scientists used the Atacama Large Millimeter / submillimeter Array (ALMA), one of the world’s most powerful telescopes located in Chile, to make this discovery.
Researchers found the object to be a large, stable rotating disc, clocking in at a whopping 70 billion times our sun’s mass. The disk remains as it was when they discovered that the universe was just 1,5 billion years old, or 10 per cent of its present age.
Some say a mechanism known as the “cold-mode accretion” may have formed the galaxy.
