Life on every planet (in fiction)

The Astronomical Society of the Pacific offers an annotated collection of science fiction with good science in it. What I found most intriguing is that there is no planet in the solar system where clever science fiction writers (many of them scientists), have NOT managed to come up with a plausible kind of life. From an intelligence in the Sun to a being adapted to frozen planets with a body of ice and a liquid-helium compound for blood, there's no limit to where the scientific imagination has taken us.
