Scientists are peering into the past and uncovering new clues about the early universe. Since light takes a long time to travel through space, they are now able to see how galaxies looked billions of years ago. The astronomers have discovered that spiral galaxies were more common in the early universe than previously thought. The scientists found that nearly 30% of galaxies have a spiral structure about 2 billion years after the universe formed. The discovery provides a significant update to the universe s origin story as previously told using data from NASA s Hubble Space Telescope.
