Moons of jupiter

Thanks to a surface covered in liquid water, Jupiter's moon Europa serves as the prime suspect for bodies in our solar system harboring extraterrestrial life.

However, a new study estimates the level of oxygen in Europa's seas may be high enough to support fish-sized life. Hello, alien sushi.
