The Comet is a fanzine that was published in 1930 in the U.S.A. by Raymond Palmer.
The Comet is widely acknowledged as being the first science fiction fanzine ever published. It was edited by Raymond Arthur Palmer and published by the Science Correspondence Club. As the name of the publishers suggests, it has its origins in correspondence between science fiction fans. Naturally, the letter section of The Comet was a prominent feature of the zine, where readers discussed issues concerning science, science fiction and fiction.
Contributors to this first issue, dated May 1930, included Lilith Lorraine, among others.
After the first issue, the title changed to Science Correspondence Club Organ for the second and third issue. The fourth issue was titled Science Correspondence Club Bulletin. After the fourth issue (September 1930), A.W. Gowing assumed editorship, and changed the title to Cosmology, the title it retained until the seventeenth and final issue (1933). Editorship changed hands once again, though, for the final four issues, to Aubrey McDermott and Clifton Amsbury.
Raymond Palmer went on to edit Amazing Stories and Fantastic Adventures and a number of other magazines issued by his own publishing company.
