Scientists from the Atacama Cosmology Telescope have produced the clearest images of the universe at just 380,000 years post-Big Bang, showcasing the Cosmic Microwave Background. These 'baby pictures' show how regions of hydrogen and helium evolved over time due to gravity, leading to the formation of stars and galaxies. The Cosmic Microwave Background represents the fossilized heat from the early universe, essential for understanding cosmic history. This groundbreaking research provides unprecedented insight into the conditions that shaped the structure of our universe.
We are seeing the first steps towards making the earliest stars and galaxies.
The CMB is essentially the fossilised heat of the infant universe, allowing scientists to see the cosmos at its very first observable moment.
What looks like clouds of light are actually hills and valleys light-years across in the boiling sea of hydrogen and helium which filled the early universe.
These stunning images measure light that has travelled for more than 13 billion years to reach Earth, showing the universe as it was just 380,000 years after the Big Bang.
