Simulating the process of gas accumulation to form galaxies.
Researchers at the Niels Bohr Institute of the University of Copenhagen have witnessed the birth of the universe's first triplet of galaxies, dating back 13.3 to 13.4 billion years.
Through the James Webb telescope, a team of experts observed signals coming from large volumes of gas accumulating and feeding into a mini-galaxy that is in the process of accreting and forming, according to a report published in the journal Science .
While this is how galaxies are theoretically and computer-simulatedly formed, the process had never been observed in reality until recently.
"We can say that these are the first direct images showing the birth of galaxies," according to the research team leader, Professor Kasper Elm Heintz of the Niels Bohr Institute.
Researchers estimate that the birth of this trio of galaxies occurred approximately 400-600 million years after the Big Bang, meaning during a period when the universe was about 3-4% of its current age.
"In the first few hundred million years after the Big Bang, the first stars appeared, before stars and gas began to accumulate into galaxies. That's the process we observed," according to Professor Darach Watson, a member of the research team.
