In "Solaris," a densely ruminative novel first published in 1961 — and made into films by Andrei Tarkovsky (1972) and Steven Soderbergh (2002) — contact is made with a dangerous and unknowable alien intelligence in the form of a plasma ocean surrounding a distant planet. As they attempt to understand the organism, astronauts aboard a space ship are plagued by hallucinations drawn from their own memories.
