The telescope Her James Webb NASA discovered a ‘Cosmic Vine’ originating from the early universe and running through space in an arc shape, containing about 20 galaxies.
The Live Science states that a relevant study has been published in the database arXiv and raises questions about the formation of the universe’s largest structures.
This particular “Cosmic Vine” is estimated to have over 13 million light-years long and about 650,000 light-years wideat a time when our Milky Way is about 100,000 light-years across.
All the galaxies observed in this galaxy cluster presented redshift about 3.44which means that the light emitted traveled between 11 and 12 billion years before reaching James Webb’s lens.
According to astronomers, the “Cosmic Vine” it is “significantly larger” than other galaxy groups observed so early in the universe’s history. The galaxy group has an estimated mass of about 260 billion solar masses and counting.
Researchers report that the “Cosmic Vine” appears to be located in formation phase of a galaxy cluster– these are the most massive gravitationally bound structures in the universe, with masses typically ranging from hundreds of billions to four billion times the mass of Earth’s sun. Two galaxies, however, were labeled “dormant”.
The authors noted that they don’t often find such large galaxies that have already run out of star-forming gas in the ancient universe. One possibility is that both galaxies are the results of recent galactic mergers, with cosmic collisions triggering wild bursts of star formation that depleted most of the galaxies’ available gas about half a billion years before James Webb’s observations, the researchers wrote .
