In a groundbreaking achievement, astronomers have captured the clearest images yet of the universe's infancy, offering a profound glimpse into its formative years. Utilizing the Atacama Cosmology Telescope (ACT) in Chile, researchers have observed the cosmos as it appeared approximately 380,000 years after the Big Bang. These images reveal the intricate formation and movement of primordial hydrogen and helium gas clouds, shedding light on the processes that eventually led to the creation of stars and galaxies, including our own Milky Way. The analysis indicates that the observable universe spans nearly 50 billion light-years and contains a mass equivalent to about 1,900 zetta-suns, with dark matter and dark energy comprising the predominant components. These findings, which align with the Lambda CDM model, reinforce our current understanding of cosmology and show no signs of new particles or unusual physics. The results were presented at a meeting of the American Physical Society and are slated for publication in the Journal of Cosmology and Astroparticle Physics. Looking ahead, the ACT's successor, the Simons Observatory, has commenced operations and is expected to provide even more detailed images of the early universe.
