Telescope reveals earliest-ever 'baby pictures' of the universe: 'We can see right back through cosmic history'
- The clearest images of the infant universe have been released by astronomers, confirming the leading theory of the universe's evolution.
- The new images captured light that traveled for over 13 billion years to reach the Atacama Cosmology Telescope in Chile, showing the universe at just 380,000 years old.
- These images reveal the cosmic microwave background emitted as the universe emerged from its hot, opaque state after the Big Bang, marking the first accessible snapshot of the universe's infancy.
- They show the formation and motions of gas clouds that eventually turned into the stars and galaxies we see today.
- The observations extend the observable universe almost 50 billion light-years in all directions from Earth and suggest the universe contains as much mass as 1,900 'zetta-suns.'
- Of this mass, 1,300 zetta-suns come from dark energy causing the universe's accelerating expansion, while 500 zetta-suns come from dark matter.
- The Lambda cold dark matter (Lambda CDM) model describing the universe's evolution was found to be consistent with the early universe data, with no signs of new particles or unusual physics.
- The observations also provided precise measurements of the universe's age and rate of expansion, concluding with the now-decommissioned ACT telescope.
- The Simons Observatory, the ACT's successor, began operations and aims to capture even more detailed images of the early universe.
- The latest findings strengthen the standard model of cosmology and provide valuable insights into the evolution of the universe.
