Ganymede

In the fourth chapter, we delve into an extensive examination of Ganymede, the largest moon within our Solar System and a fascinating ocean world. Our exploration begins with an in-depth review of its initial discovery by Galileo, followed by a comprehensive analysis of the observations made over the centuries preceding the era of spacecraft exploration. The observations conducted by spacecraft which provided unprecedented insights into Ganymede’s intriguing features and geological characteristics are reviewed in detail. We also review the different phases of ice that exist and how some of them could be present within the moon. Furthermore, we provide insights into the lines of evidence bolstering the hypothesis that Ganymede harbors a subsurface ocean concealed beneath its icy shell, endeavoring to elucidate its nature and characteristics. Additionally, we explore the concept of habitability within the context of Ganymede, contemplating the potential conditions that could support life within this giant moon.
