What are the key findings from the new images of the early universe generated by the Atacama Cosmology Telescope, and what is their immediate significance for cosmology?

New images from the Atacama Cosmology Telescope (ACT) offer the clearest visualizations yet of the universe's infancy, around 380,000 years after the Big Bang. These high-resolution maps reveal the distribution of hydrogen and helium, and their movement, allowing for more precise measurements of the universe's age and expansion rate. This data provides an independent check of existing cosmological models.
