Galaxies are vast collections of stars, gas, and dark matter that trace the underlying structure of our universe. For decades, astronomers have been piecing together the story of how the first galaxies grew and transformed into the massive ellipticals we see today. The James Webb Space Telescope, launched in late 2021, has already revolutionized this field: its deep, sharp view into the infrared lets us directly glimpse the era of cosmic dawn. In this talk, we’ll dive into one of the biggest surprises from JWST so far: the discovery of enormous quiescent galaxies astonishingly early in cosmic history.
