A recent observation has challenged the current theory about the way galaxies formed in the early days of the universe. Many cosmologists believe that the universe began with a Big Bang. Therefore, galaxies forming in the early universe could experience very chaotic physical processes, which made them appear disordered. However, the new study has cast serious doubt on this picture. Scientists observed a star-forming galaxy called ALESS 073.1, which is 12.5 billion light-years away and appears very much like a typical mature galaxy. Due to ALESS 073.1’s great distance from Earth, its light takes billions of years to reach us. This enabled the team to explore the galaxy’s formation and evolution during its infancy. The team, led by scientists at Cardiff University, used the Atacama Large Millimeter/submillimeter Array (ALMA) telescope to analyze the kinematic properties of ALESS 073.1. With careful analyses, the team obtained one of the sharpest direct images …
