In Star Trek V: The Final Frontier, Sybok claims that Sha Ka Ree contains God.
Sybok is Spock's half-brother and a Vulcan who has rejected the traditional discipline of suppressing emotion. He gathers followers by relieving their pain and promises them a meeting with the divine being he believes lives beyond the Great Barrier at the center of the galaxy.
After hijacking the Enterprise-A, Sybok leads the ship to Sha Ka Ree, a legendary planet named in a way that echoes the human idea of paradise. The crew discovers a powerful entity there, but the being's demand for the starship and its attempt to use violence reveal that it is not the benevolent creator Sybok expected.
The title Star Trek V: The Final Frontier refers to this spiritual and literal journey. The film was released in 1989 and directed by William Shatner, who also played Captain James T. Kirk. Sha Ka Ree is a fictional world, not the name of a known astronomical object.
