Saturn’s moon Enceladus, Jupiter’s moon Europa, Pluto and its moon Charon, as well as the dwarf planet Ceres are potential homes for extra-terrestrials, scientists at University of Texas at San Antonio and the Southwest Research Institute claim.
It’s all down to a process called radioalysis, which experts believe could breed life across the universe.
All that’s needed is a rocky core and water molecules – something scientists reckon our solar system has plenty of.
The study found that a the rocky cores of some planets and moons emit radiation which break up water molecules and in turn feed microbial life.
