“Nightfall,” Isaac Asimov, 1941 – A culture that has never seen the night due to the presence of six suns experiences nightfall for the first time.
Comments: “According to Asimov’s autobiography, Campbell asked Asimov to write the story after discussing with him a quotation from Ralph Waldo Emerson: ‘If the stars should appear one night in a thousand years, how would men believe and adore, and preserve for many generations the remembrance of the city of God!’” (Wikipedia). Considered one of the best sf stories by many. See, for example, the introduction by Harry Harrison in The Mirror of Infinity: A Critics’ Anthology of Science Fiction.
