James Webb Space Telescope discovered the known farthest galaxy – Cyprus Newspaper

James Webb Space Telescope (JWST) has observed the most remote galaxy that emerged only 280 million years after the formation of the universe. This discovery once again demonstrated JWST’s capacity to expand the curtain of the earliest stages of cosmic time.

The newly discovered galaxy was called “MOM-Z14 .. The discovery was carried out within the scope of Mirage (or Miracle) spectroscopic research to observe the early universe.

Redshift of the galaxy (redshift) was determined as Z = 14.44. This value shows that the light of the galaxy spread about 13.5 billion years ago.

Previously, the record was in the hands of the Jades-GS-Z14-0 galaxy with Z = 14.32. However, MOM-Z14 carried the boundaries of the observable universe even further.

According to the study, which was prepared under the leadership of Rohan Naidu of the Institute of Astrophysics and Space Research at MIT Kavli and published in Arxiv.org, this galaxy may have been very close to the period of the first stars of the universe.

“JWST has unexpectedly revealed a population of bright galaxies. This raised the basic questions about the formation of galaxy,” the researchers said.

The light from the stars is not a black hole

In spectroscopic examinations, the light of MOM-Z14 was mostly caused by stars. In other words, the galaxy does not have the light of the active galactic nucleus (AGN) spread through a super -mass black hole, but a glitter from many and possibly super -mass stars.

In addition, the galaxy’s nitrogen-carbon ratio is higher than the Sun. This ratio points to a chemical composition similar to the old global star clusters of the Milky Way. Researchers say that this similarity offers clues that connect the galaxy evolution throughout cosmic time.

There may be a connection between chemistry and morphology

Two different structures were observed in MOM-Z14 and similar galaxies: Point (compact) and spread (wide) morphologies. Compact galaxies are broadcasting strong nitrogen, and those in the spread structure are weaker in terms of nitrogen. This suggests that there may be a direct relationship between galaxy chemistry and physical structure.

New telescopes can reveal more

The authors of the study state that galaxies such as MOM-Z14 can lead to radical changes in our understanding of the formation of galaxy. If it is not canceled, tasks such as Nancy Grace Roma Space Telescope, which is planned to be launched in the coming years, can make it possible to explore hundreds of such galaxies.

Researchers write the following in the result sentence:

“JWST brings our observable horizon to the earliest periods of the universe to the points that we cannot imagine.
