Between December 1952 and January 1954 six issues of this US Pulp magazine edited by R. A. W Lowndes and published by Columbia Publications were released.

 The inclusion of two two-part noteworthy articles by James Gunn: "The Philosophy of SF" (March – June 1953) and "The Plot Forms of SF" (October 1953 – January 1954) compensated for the otherwise unremarkable fiction.

 In Britain, three numbered issues were reprinted in 1953.
