Source-derived summary

Siderella, originally Iso-Zen, also known under many other names, was a French UFO religion. It was founded and led by Jean-Paul Appel, who founded the group in 1966 in Paris, France. The views of the group involved ufological and New Age themes, and took elements of Buddhism and Tantrism. They believed an apocalypse was imminent and that members of the group would be saved by aliens and taken to Alpha Centauri.

Members of Siderella lived communally, and preached consciousness expansion and preparing for contact with aliens, which involved group sex. They worshipped aliens. It counted two notable comic book artists among its membership, Jean Giraud and Sergio Macedo. Their advertisements involved science fiction, and in 1982 they published a comic book, Timeless Voyage, which was based on their beliefs. Guery claimed he had been conceived through alien intervention and that at the age of 12 he had been contacted by extraterrestrials.

Most active in France, though also present in other European countries, they moved to Tahiti in the 1980s.

Editorial analysis

Why this record matters

“Siderella” is worth following because a concise public description often conceals a longer documentary argument. Here, Siderella and religion provides the most credible route into that argument.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q134696104. None of the 2 selected statements returned an explicit reference. The first chronological checks are 1966 and 1982.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
