2001 Nights (2001夜物語, Nisen'ichi Ya Monogatari) is a science fiction manga series written and illustrated by Yukinobu Hoshino. It was originally serialized in Futabasha's Monthly Super Action starting from June 1984 and collected into three bound volumes by Futabasha, released between August 18, 1985 and October 24, 1986. The series was licensed for an English-language release by Viz Media and published in North America starting March 22, 1996. 2001 Nights is largely inspired by classic hard science fiction, with many visual homages to previous science fiction novels and films.
2001 Nights consists of several loosely connected short stories, all taking place in the same timeline, with the whole series spanning several hundred years. Many of the stories are related to each other (even across books), each building upon the achievements of the previous ones. The stories are often (but not always) scientifically plausible, recalling a lot of the early science fiction of the 1950 and 1960 eras.
