Io Probably Doesn’t Have a Global Magma Ocean After All - eos.org

Recent research challenges the long-held belief that Jupiter's moon Io possesses a global magma ocean beneath its surface. Instead, new findings suggest that the moon's geological activity may stem from localized pockets of molten rock rather than a vast, interconnected ocean. This shift in understanding emphasizes the complexities of Io's geology and highlights the importance of ongoing exploration and study within our solar system.
