Alleged extraterrestrial entities. Prior to the 1970s such entities usually claimed to be inhabitants of the Moon, Mars, Venus, or another planet of this solar system. In the last two decades such claimed inhabitants have tended to come from far distant solar systems. Space Intelligences (SIs) allegedly communicate telepathically to chosen individual channels or through Spiritualist mediums. The most consistent Space Intelligences are those that communicate to the several contactee organizations such as the Raelian Movement, Unarius-Science of Life, the Aetherius Society, and Mark-Age, Inc.
