Milky Way Galaxy has evolved gradually according to astronomers. The finding was made by a team which was led by Dr. Nicholas Scott and Jesse van de Sande, from Australia’s ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) and the University of Sydney.
Dr. Scott explained that their observations specify that the Milky Way’s thin and thick discs didn’t emerge out because of a gigantic mash-up, rather it is a sort of s usual path of galaxy formation and its typical evolution.He further added that from these results they think that galaxies with the Milky Way’s particular structures and properties can be easily described as the usual ones. This conclusion was published in the book called “The Astrophysical Journal Letters.”
Co-author Professor Ken Freeman from the Australian National University stated that this is an important step forward taken in understanding that how disk galaxies must have assembled long ago. We know a lot about how the Milky Way must have formed, but there was always the worry that the Milky Way is not a usual spiral galaxy.
