Classification of the different galaxies based on their morphology

Classification of the different galaxies based on their morphology must satisfy two main conditions. First, it must assist the astronomer to identify the space object and secondly, it should provide in-depth information about this space object. Classification of galaxies based on their visual appearance is one of the most imperative aspects during their study. Generally, galaxies are classified as elliptical, spiral or irregular galaxies (Schneider 92). It is generally thought that galaxies begin as elliptical disks that later spread and flatten to form spirals and flat galaxies (Schneider 89). In order to study different galaxies, a deep insight to their formation is necessary (Dick 20). This is achieved by studying their images
