There are popular movie franchises, and then there’s "Star Wars." Entire generations grew up on the galaxy far, far away, forming a hardcore fandom in the process. But despite all the space opera content including movies and TV shows on Disney+, there are still a few ongoing mysteries about George Lucas’ beloved universe. And the "Star Wars" franchise recently explained how Yoda was able to hide on Dagobah without the Empire finding him.

When Yoda was introduced in "Empire Strikes Back," he’s a small but surprisingly wise and powerful Jedi living in exile on Dagobah. The prequels revealed how he got there, but some "Star Wars" fans have been wondering how Vader never sensed him– especially since according to "Star Wars’" map, Dagobah is fairly close to the planet Mustafar where Vader’s castle is. A new short story titled "The Light That Falls” was included in "From a Certain Point of View: Return of the Jedi" (via ScreenRant) reveals that the answer is actually connected to the Dark Side Cave from "Empire Strikes Back."
