Titanic Energy
A lake of liquid methane glistens beneath the orange sky of Titan in this artist's concept. The big moon of Saturn appears to have many large lakes of liquid hydrocarbons, as well as giant dunes made of grains of hydrocarbon ice. The energy content of these compounds far exceeds the known hydrocarbon energy reserves on Earth, according to researchers who have studied readings from the Saturn-orbiting Cassini spacecraft.
