Farsight

Farsight (also called clairvoyance, far sight or farseeing) was the ability requiring training in the Control and Sense skills. Force users employing farsight were able to see visions of people or places in their mind, as it appeared at the same time they were observing. The visions included the immediate surroundings, allowing the Force user to determine if a friend was in danger, or what had occurred on a planet in their absence.

Palpatine used this skill to discover that Darth Vader was in danger after his fight with Jedi Master Obi-Wan Kenobi. He also used it to set his traps for the Jedi, keeping himself several steps ahead. During a meeting aboard the Death Star, when Vader told Admiral Conan Antonio Motti to not place too much faith in the Death Star's capabilities and implied even its destructive power was insignificant compared to the power of the Cosmic Force, Motti insubordinately retorted that Vader's devotion to the Force didn't have him find the stolen Death Star plans while sarcastically referring to such as clairvoyance before Vader nearly choked him.

One of the first Force powers Yoda taught to the young Luke Skywalker was farseeing. He used this ability to sense that his friends were in danger on Bespin. Despite the advice of Yoda and the Force ghost of Obi-Wan Kenobi, he decided to intervene.
