Summary

Story summary

The James Webb Space Telescope identified MoM z14 as the most distant galaxy, with light traveling 13.5 billion years, revealing the universe when it was less than three percent of its age.
MoM z14 is unexpectedly bright for its age, challenging models of early galaxy formation and suggesting clusters were harsher earlier.
Researchers at the University of Waterloo identified the farthest jellyfish galaxy dating to 8.5 billion years ago.
