A NASA investigation discovered that there would be a salty and underground ocean in our solar system, which would be located in one of Jupiter’s 95 moons. These water masses could be clear signs that there are bodies in space that would be able to house life. For this reason, Calisto, one of the natural satellites of this fifth planet of the Solar System, is being so analyzed.
The team headed by Corey J. Cochrane counted in their work published in Agu Advances that used data from the Galileo mission to review magnetic measurements taken for several flying over the second largest moon in Jupiter. These are data from 1990, where they found a magnetic induction signal that indicated an interaction between the magnetic field of the gaseous giant and a superficial conductive layer on the moon.
After an exhaustive work in the face of the difficulty in analyzing its gaseous atmosphere, they concluded that the magnetic observations were not product only from the ionosphere. Thus, they determined that there is an underground ocean.
