James Webb Space Telescope marks three years of groundbreaking discoveries in astronomy

The James Webb Space Telescope (JWST) has made significant discoveries in its first three years, transforming our understanding of the universe. It has identified the most distant galaxy, dating back to when the universe was just 300 million years old, revealing efficient early star formation. JWST has also uncovered unusual chemical compositions in early galaxies, including unexpected nitrogen levels. This suggests that our current models of star and galaxy formation are incomplete, indicating new processes in the early universe. Additionally, JWST has detected mysterious compact red sources, initially thought to be dense galaxies. These may represent a new stage in the evolution of galaxies and supermassive black holes, prompting further investigation into their nature and origins.
