Scientists monitor the most distant galaxy discovered in the universe

Galaxy

 Astronomers have identified the most distant galaxy discovered from the universe, in the form of a red glowing body, which formed 330 million years after the "Big Bang".


It took the faint light of the galaxy traveling 13.5 billion light-years to reach us on planet Earth.


The galaxy's discoverers called it "HD 1", and they indicated in their research published in the Astrophysical Journal that they were not sure if it was a stellar galaxy, but they identified a supermassive black hole in its center.


According to the scientist Fabio Paccucci of the "Harvard-Smithsonian" Center for Astrophysics, the exact answer to the details of the galaxy, which is located at a very large distance, is very difficult. Detecting things in the early universe is difficult."


And according to the "Science Alert" website, which specializes in scientific news, four telescopes were used to observe the galaxy, and researchers took 1,200 hours of observation.


Commenting on the discovery, astronomer Yuichi Harikan of the University of Tokyo, Japan, said: "It was very difficult to find the galaxy among more than 700,000 objects. The red color of HD1 matches the expected characteristics of a galaxy 13.5 billion light-years away."


Galaxies' red color is known as "redshift", and it occurs when a light source moves away from us, and this leads to an increase in the wavelength of light coming from this source towards the red end of the electromagnetic spectrum, which is why it is called.


Because the universe is expanding, other galaxies appear to be redshifted, knowing that the greater the distance in spacetime, the greater the "redshift".


The researchers hope that the information and images obtained from the James Webb Space Telescope will help them to reveal the nature of the light in this galaxy, and reveal more secrets about the emergence and formation of the universe.
