Alien Worlds was published on a bi-monthly schedule by
Pacific Comics from December 1982 to April 1984 for eight issues, with a single issue of spin-off
Three Dimensional Alien Worlds published in July 1984. After Pacific went bankrupt, two final issues were published by
Eclipse Comics in November 1984 and January 1985. Eclipse considered continuing the title but instead opted to create
Alien Encounters with a variety of writers. Instead Jones took
Alien Worlds to
Blackthorne Publishing, who produced a
one-shot featuring reprints of stories taken from earlier issues. In 1987 Eclipse struck a deal with Jones & Campbell's new packaging operation Bruce Jones Associates for new prestige format bi-annual versions of
Alien World, cancelling
Alien Encounters to make room. Only a single issue of the new format was produced. Following Eclipse's bankruptcy in 1995, the company's assets were purchased by
Todd McFarlane. Believing that the deal included the names of the Jones/Campbell anthologies, he teased a series called ''Todd McFarlane's Alien Worlds
in the 1998 one-shot Total Eclipse'', but the comic would never appear. ==Content==
