The Sirens of Titan

The Sirens of Titan

Image Credit: NASA, ESA, and the Hubble Heritage Team (STScI/AURA). Discovered in 1655 by Christiaan Huygens, Titan was the first moon discovered to orbit a world other than Earth or Jupiter. But that doesn't mean the surface of Titan looked very much like the surface of our Moon. Liquid methane in those regions wouldn't last long and ought to boil off, so knowing what we know now, a methane lake near a tropical region of Titan would be a surprise. Maybe, just maybe, Titan is another world in the Solar System where life, no matter how primitive, has found a way.
