According to RCO News Agency, quoted by Independent, ALMA telescope observations revealed a very hot, unknown factory of star formation that existed less than a billion years after the big bang. In this regard, a group of international researchers analyzed the light emitted from the primary galaxy Y1, which takes 13 billion years to reach Earth.
The discovery helps solve the long-standing puzzle of how galaxies grew so rapidly in the early universe.
Tom Bucks, a researcher at Chalmers University in Sweden and the leader of this study, says: “We are looking at a time when the universe was making stars much faster than it is now.” Previous observations indicated the presence of cosmic dust in this galaxy. It is the most distant galaxy on which luminous dust has been detected.
He further added: For this reason, we suspected that this galaxy probably contains a different type of very hot star factory. To be sure, we decided to measure its temperature.
By measuring the temperature of the very hot cosmic dust, astronomers were able to confirm that it is an active star-making factory.
Astronomer Yuichi Tamura of Nagoya University in Japan says: Although this is the first time we have observed a galaxy like this, we believe that there are probably many other examples of it.
Y1 is forming stars at a very high rate of 180 stars per year, which is unsustainable on cosmic scales. The Milky Way, on the other hand, produces only one star per year.
“We still don’t know how common such processes are in the early universe, so we plan to look for more examples of similar star factories in the future,” Bax says.
