Unveiling the Secrets of the Early Universe with JWST

Using the James Webb Space Telescope (JWST), astronomers have observed an ultra-faint galaxy in the cosmic dark ages, providing insights into the early universe. The galaxy, located 13 billion light-years away, was detected using spectroscopy and photometric redshift analysis. The observations suggest that the galaxy formed stars at a high rate in its early history, but then stopped abruptly. The findings shed light on the processes that shaped the early universe and the formation of galaxies.
