They suggest stars developed much faster and more efficiently than we thought.
“The merger hasn’t finished yet. We can tell this by the fact we still see two components. The long tail is likely produced by some of the matter being cast aside during the merger. When two things merge, they sort of throw away some of the matter. So, this tells us that there’s a merger and this is the most distant merger ever seen,” says Dr. Boyett.
But it is not only the size of the galaxies and the speed with which they grew that surprises Dr. Boyett. His paper for the first time describes the population of stars that make up the merging galaxies – another detail made possible by JWST. Most studies of these very distant objects show very young stars, but this is because the younger stars are brighter and so their light dominates the imaging data. The JWST, however, allows for such detailed observations the two populations can be distinguished.
