Is Vulcan Real? Its Star Is, But Scientists Can't See Habitable Planets

In the fictional universe of "Star Trek," the alien Spock comes from a world called Vulcan in the triple-star system 40 Eridani. Vulcan was destroyed in a previous movie, forcing Spock's race to immigrate to a planet called New Vulcan. While Vulcan is one of the most well-known worlds in science fiction, the planet is entirely fictional.
