The I.A.U. (Interplanetary Information Assimilation Unit) is an ancient extraterrestrial device. It is as long as three school buses, and is equipped especially for it's task of gathering knowledge. It boasts a large, blue camera-like eye, used as a telescope to monitor the planets it orbits (Currently, that planet is Earth, and it is attracted to monitor Gravity Falls, due to it's high supernatural activity) and utilizes highly advanced polygraphs (Commonly known as "Lie Detectors") to monitor the electrical activity in any living creature's mind, enabling it to read minds. It may at any given moment, launch a pod with an "up-close" probe, if the Unit requires any contact with Earth. It's motives for information gathering are unknown.
