WebIn 1926, while developing a classification system for galaxies, Hubble discovered an odd fact: Almost every galaxy he observed appeared to be moving away from the Earth. He knew this because the light coming from the galaxies exhibited redshift. Light waves from distant galaxies get stretched by the expansion of the Universe on their way to Earth.

WebNov 24, 2024 · In the prevailing theory, the formation of a galaxy can be divided into three stages: 1. A ‘primordial collapse’ of matter into a clump in the early, expanding Universe. 2. Hierarchical structure formation of larger clumps from smaller clumps. 3. A smoother evolution through internal processes such as the formation of spiral arms. WebThe first really robust theory was developed by C. C. Lin and Frank Shu in papers of 1964 and 1966. They proposed that spiral arms were the manifestations of spiral density waves in the gas and stars of a galaxy. This theory, or variations on it, seems to be the most resilient even today.
