Author Héctor Germán Oesterheld and artist Francisco Solano López worked together to create the science fiction Argentine comic El Eternauta. Prior to its collection and publication as a book, it was initially serialized in the magazine Hora Cero Semanal between 1957 and 1959.

The narrative centers on Juan Salvo, his relatives, and companions as they fight to endure an unusual and lethal snowfall in Buenos Aires, ultimately disclosed to be the initial phase of an extraterrestrial invasion.

Oesterheld is a character in the story, and Juan Salvo narrates his experiences to him in order to present the plot. Themes of resistance, collective endurance, and societal breakdown arise as survivors struggle against the deadly snow and the encroaching aliens.

El Eternauta, which mirrors the political turmoil in Argentina during that era, has been viewed as a symbol of resistance against authoritarian governments.

The graphic novel has experienced several adaptations and sequels throughout the years, including a politically influential 1969 version by Alberto Breccia. Many nations, such as Italy, France, and Spain, have released translations and reprints of the original comic because of its immense popularity. The initial English-language edition, released by Fantagraphics Books in 2015, received the Eisner Award for Best Archival Collection/Project.

Facts about El Eternauta highlight its acclaim for realistically portraying Buenos Aires, featuring well-known city landmarks within the science fiction backdrop. Moreover, the work has been recognized for introducing the "social science fiction" genre in Latin America, merging speculative aspects with realistic social and political critique.
