The Unexplained: Mysteries of Mind, Space, & Time was a popular partwork magazine published by Orbis Publishing in the United Kingdom, between 1980 and 1983. It ran to 156 issues, with issue 157 being an index to the collection, and dealt with the paranormal and mysteries such as UFOs, the Bermuda Triangle, ghosts, spontaneous human combustion, the Cottingley Fairies, ancient knowledge, sea monsters, the Yeti, weird coincidences, stone circles, contact with the dead, and notable historical characters linked to the occult. The magazine was published as a journal, with page numbering continuing from one edition to the next. When the magazine ceased publication, a refund was offered if the consumer returned the covers.
The magazine was edited by Peter Brookesmith, and consultants included Dr. J. Allen Hynek and Professor A. J. Ellison. The editorial director was Brian Innes, who had previously worked on Man, Myth & Magic: An Illustrated Encyclopedia of the Supernatural.
A complementary version was published in France, entitled L'Inexpliqué, which contained differently written articles. This series was published in 8 to 26 volumes, depending on whether the edition were British or French.
Articles from the magazine were later published in book form during the late 1980s by various publishers, including Black Cat, Caxton, and St. Michael's books. Titles included: When the Impossible Happens (1984) and Out of this World: Mysteries of Mind, Space, & Time (1989).
