Between Titan’s Icy Surface and Blazing Core, There Just May Be Life | Science Not Fiction | Discover Magazine: "While we may have to look to the stars for signs of intelligence, the search for life is a somewhat different — though obviously related — matter and we shouldn’t forget that there are many potential abodes of life with in our own Solar System. Surprisingly many are in the outer solar system, and receive only a faint glimmer of Sol’s life-giving radiation. Given the diversity of extremophile organisms discovered in the depths of Earth’s oceans — as well as other places that would initially seem counter-intuitive — organisms that live their entire lives never seeing a single photon from the Sun, it appears that the presence of liquid water is much more of a requirement for life than is sunlight."
