Summary:
- Callisto, one of Jupiter's moons, has a thick icy crust covering its surface. Using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope, scientists have been able to peer beneath this icy layer and study the moon's interior.
- The observations reveal that Callisto's interior is likely composed of a rocky core surrounded by an icy mantle, similar to the structure of Earth. This provides valuable insights into the formation and evolution of this Jovian moon.
- The data from ALMA also suggests that Callisto may have a subsurface ocean, which could have implications for the potential habitability of this moon. Further research is needed to confirm the existence and characteristics of this potential subsurface ocean.
