From: Star Trek: The Next Generation
Caption: The El-Aurian Guinan
Planet: name unspecified. A humanoid species of "listeners" whose individual life-span can last well over 500 human years. El-Aurians appear to have an awareness that supersedes the normal flow of time and space, and while they might not be capable of explaining their sensing abilities, they detect time changes that would be impossible for nearly all other species to pick up. This trait has been recognized within individuals who were subjected to the nexus energy ribbon phenomenon, which may be related to the sense.
The El-Aurians were driven from their homeworld long ago by the Borg collective's assimilation.
