Jupiter's early migration through the inner solar system caused gravitational mayhem, but it ultimately settled to allow Earth to form in a relatively quiet neighborhood.
Saturn's icy moon Enceladus is showing definite signs of hydrothermal activity -- similar activity that is found along deep sea vents on Earth where water is heated and minerals are formed.
Chemical engineers have created a theoretical model of a type of alien cell that might be able to support life on Titan.
In a sneak peek of a possible future mission to Saturn's moon Titan, NASA has showcased their vision of a robotic submersible that could explore the moon's vast lakes of liquid methane and ethane.
