James Webb Telescope gives a peek into 'baby years' of 7 Galaxy clusters

Since its launch, the James Webb Space Telescope has been astonishing the world with its capabilities despite being in service for less than two years. NASA's $10 billion space telescope has been capturing breathtaking images of far-off galaxies, star clusters, ancient black holes and other celestial objects. Now, it has added another feather to its cap by giving us a glimpse into the past of galaxies, when they wer babies, and how they formed, assembled and may look now.

A recent study has shed light onto the early formative, 'baby years', of galaxies. According to NASA, protocluster of seven galaxies has been confirmed at a distance that astronomers refer to as redshift 7.9, or a mere 650 million years after the Big Bang.

After analyzing the collected information, researchers predicted the eventual growth of the young cluster and concluded that it is probable that it will grow both in size and mass until it resembles the Coma Cluster, a large galaxy cluster with over 1000 identified galaxies. Therefore, in time, this galaxy cluster could become one of the densest known galaxy clusters in the universe.

Takahiro Morishita of IPAC-California Institute of Technology and the lead author of the study which is published in Astrophysical Journal Letters said, “This is a very special, unique site of accelerated galaxy evolution, and Webb gave us the unprecedented ability to measure the velocities of these seven galaxies and confidently confirm that they are bound together in a protocluster.”

Moreover, the spectral data collected by the James Webb Telescope allowed astronomers to model and map the future development of the gathering group, from the beginning to all the way to our time in the recent universe.
