Journey to Maisie's Galaxy

The James Webb Space Telescope (JWST) has redefined our understanding of the cosmos, bringing to light profound mysteries. Recently, the JWST introduced us to Maisie's Galaxy, one of the universe's earliest formations, emerging about 390 million years post-Big Bang. This discovery, a part of the Cosmic Evolution Early Release Science Survey, pays homage to its lead investigator's daughter, Maisie Finkelstein. The revelation comes with crucial implications, considering the universe's swift expansion and the complexities of dating ancient galaxies.
