The James Webb telescope has discovered six huge galaxies in the early universe at once, the mass of which exceeds the solar system by about 100 billion times. According to Naked Science, the discovery was made as part of a scientific program to study the early Universe CEERS.
It is generally accepted that the first galaxies began to appear only a couple of hundred million years after the Big Bang. However, none of them were as massive and complexly structured as today. They were formed by the merger of smaller galaxies, and this process stretched over billions of years.
However, the data obtained contradict such views on the past of our Universe.
The telescope immediately discovered six galaxies that existed already 500-700 million years after the Big Bang and at the same time had masses up to hundreds of billions of solar masses.
“The first thought was that this was some kind of mistake,” said one of the researchers, Ivo Labbe, “but despite all attempts, it was not possible to find it.”
Another author of the new work, Joel Leia, noted that these objects are much more massive than one might expect. Astronomers expected to see small, young galaxies, but found galaxies as mature as ours, in the era that is considered to be the very beginning of the universe.
One of the most curious differences from modern large galaxies was their small size. So, one of the galaxies contains almost as many stars as ours, but at the same time it is 30 times more compact than it.
Experts intend to re-check the data. They do not exclude that some of the six amazing objects are not galaxies, but forming supermassive black holes.
