Astronomers using the ALMA telescope have detected oxygen in the most distant galaxy known, challenging previous beliefs about the speed of galaxy formation in the early universe. The galaxy, JADES-GS-z14-0, was found to be more chemically mature than anticipated, with ten times more heavy elements than expected. This surprising discovery suggests that galaxies can form rapidly after the Big Bang. The precise measurements made with ALMA have refined our understanding of distant galaxy properties, showcasing the synergy between ALMA and the James Webb Space Telescope in unraveling the mysteries of galaxy formation.
