Astronomers have monitored the farthest galaxy ever discovered, 13.5 billion light-years away from Earth, according to a study published yesterday, and its results must be confirmed through more advanced observations.
After more than 1,200 hours, during which the sky was observed through four telescopes, “HD1” was observed, a very bright object “the red color matches the characteristics of a galaxy 13.5 billion light years away,” according to what was explained by the discoverer of the galaxy Yuichi Harikanh in a statement published by the Royal Astronomical Society on the sidelines of the study.
Additional data collected by the ALMA observatory in Chile confirmed the results of the new study. The “HD1” galaxy is farther away than the “GN-z11” galaxy, which until the discovery of “HD1” was the farthest galaxy ever, by a hundred million years.
The HD1 galaxy was formed 300 million years after the Big Bang, the period of the emergence of the universe, and the light emitted from it took 13.5 billion years to reach Earth.
The authors of the study therefore put forward two hypotheses. The first indicates that the galaxy would have constituted a fertile ground for star formation in particular, and the formation of about 100 of them annually, a rate ten times higher than expected.
The second hypothesis is that there is a supermassive black hole in the center of the galaxy, which is swallowed up by huge amounts of gas and emits strong ultraviolet radiation.
