Sphere is a 1987 novel by Michael Crichton, his sixth novel under his own name and his sixteenth overall. It was adapted into the film Sphere in 1998.[1]

The story follows Norman Johnson, a psychologist engaged by the United States Navy, who joins a team of scientists assembled to examine a spacecraft of unknown origin discovered on the bottom of the Pacific Ocean. The novel begins as a science fiction story but quickly transforms into a psychological thriller, developing into an exploration of the nature of the human imagination.
