"James Webb Telescope Reveals Enormous 13-Billion-Year-Old Dead Galaxy, Challenging Cosmology"

TL;DR Summary
The James Webb Space Telescope has revealed that a speck of light observed by the Hubble Space Telescope is actually one of the oldest galaxies ever discovered, known as Gz9p3, seen just 510 million years after the Big Bang. The galaxy's massive size and mature state challenge previous understanding of early galaxies, and its complex shape indicates an ongoing merger between two galaxies. The observations also suggest a rapid accumulation of stars and metals in the early universe, shedding light on the role of galaxy mergers in stellar population growth.
