In this paper, we present the developmental strategies for the image processing operations for different types of astronomical images in various space applications. The article serves as a strong review article so that the various authors who read to it get a glimpse of the different types of image processing operations such as segmentation, pre-processing, capturing, feature extraction, classification, noise-removal & other various digital image processing operations. Image Processing in Astronomy is a significant field of research and includes a great deal of procedures relating to improve investigating the properties of the divine items or getting primer surmising from the picture information. In this paper, we give a complete contextual analysis of cutting-edge picture handling procedures applied to Astronomical Galaxy Images for further developed investigation, exact derivations and quicker examination. Image handling is one of the quickest developing advances in designing field. It has its applications in different fields. Utilizations of picture handling in various fields like Automation and Robotics, Remote detecting, Biomedical, Defense, Hand motion acknowledgment, biological investigation, Document handling, Photography, Materials Research, Space investigation and Space science
