Reevaluating the Size of Galaxies: New Discoveries Challenge Previous Assumptions.

The James Webb Space Telescope (JWST) has detected galaxies from the Cosmic Dawn period that are so massive they challenge our understanding of the Universe. The galaxies may be even more massive than previously thought, according to the latest results from the Cosmic Dawn Center. The team hypothesizes that what we’re seeing at work here is an effect that could mean these galaxies are even larger than they appear. The team found that if the galaxies were considered as an entity made up of multiple stellar groupings, the inferred stellar masses of these five galaxies would be up to ten times greater. The next step will be to look for signatures that correlate to the true mass of these galaxies that do not require high-resolution imaging.
