Research: Europa, one of Jupiter’s many moons, has an active ocean lying underneath its icy surface. If other life exists, it may be there. This moon was named after a young girl in Greek Mythology who was said to be the ‘epitome of feminine beauty.’ She was so beautiful that Zeus fell in love with her and became obsessed with possessing her. Legend has it that when she died he transformed her into a complex of stars.
