ACT Reveals Detailed Images of Early Universe

New images from the Atacama Cosmology Telescope (ACT) collaboration provide the most detailed view of the universe when it was only 380,000 years old. The images capture the cosmic microwave background radiation, offering insights into the universe's early dynamics. The ACT's observations, taken from the Chilean Andes, show the initial formations of hydrogen and helium clouds that became galaxies and stars. The images also detail light polarization, revealing the behavior of ancient gases under gravitational forces. The ACT's resolution is five times better than the Planck telescope. The measurements refine the Hubble constant, addressing discrepancies in its calculations. Five years of data collection confirm the standard cosmological model. ACT data is available in open-access repositories.
