The Visitors is a 1980 science fiction novel by American author Clifford D. Simak. It is based on a similar story of the same name, which was published in serial form in Analog magazine.
The story outlines contact between Earth and the eponymous Visitors, a group of mysterious objects from deep space. The Visitors are simple black oblong boxes, as large as buildings, which approach from space and orbit the Earth before descending to the United States. The nature of the visitors is kept rather mysterious — it is not clear if they are vehicles or living things in their own right. They are apparently unable to communicate with humans in any meaningful way; on one occasion a human is taken inside a Visitor, only to be released after experiencing a jumble of confusing colored lights and smells which he did not understand.
The Visitors are composed largely of a dense form of cellulose, and they proceed to consume a quantity of trees and plant life in the US. Eventually, they start producing vehicles, superficially resembling human cars but capable of flying using the same unknown principles as the Visitors themselves, and apparently incorporating some element of intelligence, or at least instinct, since they do not crash into things as they move. The humans assume that the Visitors have created these vehicles as a gift in return for the plant matter which the Visitors are consuming, and the novel touches on the disruption such well-meaning gifts might incur on the Earth's economic systems. Toward the end of the book, the Visitors also start producing housing units for humans, and it is even implied that something living may be inside them — perhaps even a Visitor-produced version of humans themselves.
On one level, the novel describes how communication between human and alien intelligences could well be very limited if both parties are genuinely different in psychology and physical form. Humans spend the novel largely puzzled by the Visitors' nature and motivations, and the Visitors seem to lack any real understanding of humans. Neither side ever makes any meaningful communication with the other, and the only real outcome of the contact is considerable frustration and the potential of large-scale damage to Earth's economic systems. The idea of aliens' disrupting human economies also features in the author's earlier novels Ring Around the Sun (1953), They Walked Like Men (1962), and All Flesh Is Grass (1965). The book invites comparisons to the long-term effects on the US society of the Visitors' practices, with the experiences of indigenous populations whose traditional ways of life were incompatible with the practices of European colonists.
Rosemary Herbert in her review for the Library Journal wrote that Simak has "produced one of the most engaging novels of alien invasion ever written". [1]
A Fire Upon the Deep is a 1992 science fiction novel by American writer Vernor Vinge.

Solaris is a 1961 science fiction novel by Polish writer Stanisław Lem.

The novel is one of Lem's best-known works.
Apocalyptic and post-apocalyptic fiction is a subgenre of science fiction in which the Earth's civilization is collapsing or has collapsed. The apocalypse event may be climatic, such as runaway climate change; astronomical, an impact event; destructive, nuclear holocaust or resource depletion; medical, a pandemic, whether natural or human-caused; end time, such as the Last Judgment, Second Coming or Ragnarök; or any other scenario in which the outcome is apocalyptic, such as a zombie apocalypse, AI takeover, technological singularity, dysgenics or alien invasion.
Alien invasion or space invasion is a common feature in science fiction stories and films, in which extraterrestrial lifeforms invade Earth to exterminate and supplant human life, enslave it, harvest people for food, steal the planet's resources, or destroy the planet altogether. It can be considered as a science-fiction subgenre of the invasion literature, expanded by H. G. Wells's seminal alien invasion novel The War of the Worlds, and is a type of 'first contact' science fiction.
Chariots of the Gods? Unsolved Mysteries of the Past is a book written in 1968 by Erich von Däniken and translated from the original German by Michael Heron.

The concept of self-replicating spacecraft, as envisioned by mathematician John von Neumann, has been described by futurists and has been discussed across a wide breadth of hard science fiction novels and stories. Self-replicating probes are sometimes referred to as von Neumann probes. Self-replicating spacecraft would in some ways either mimic or echo the features of living organisms or viruses.
Alien languages, i.e. languages of extraterrestrial beings, are a hypothetical subject since none have been encountered so far. The research in these hypothetical languages is variously called exolinguistics, xenolinguistics or astrolinguistics. A group of prominent linguists and animal communication scientists, including Noam Chomsky, have examined such hypothetical languages in the book Xenolinguistics: Towards a Science of Extraterrestrial Language, edited by astrobiologist Douglas Vakoch and linguist Jeffrey Punske. The question of what form alien languages might take and the possibility for humans to recognize and translate them has been part of the linguistics and language studies courses, e.g., at the Bowling Green State University (2001).
The Man in the Maze is a science fiction novel by American writer Robert Silverberg, originally serialized in the magazine Worlds of If in April and May 1968, and published in bookstores the following year. It tells the tale of a man rendered incapable of interacting normally with other human beings by his uncontrollable psychic abilities. The novel is inspired by Sophocles' play Philoctetes, with the roles of Odysseus, Neoptolemus and Philoctetes played by Boardman, Rawlins, and Muller, respectively.
First contact is a common theme in science fiction about the first meeting between humans and extraterrestrial life, or of any sentient species' first encounter with another one, given they are from different planets or natural satellites. It is closely related to the anthropological idea of first contact.
The Space Vampires is a British science fiction horror novel written by author Colin Wilson, and first published in England and the United States by Random House in 1976. Wilson's fifty-first book, it is about the remnants of a race of intergalactic vampires who are brought back from outer space and are inadvertently let loose on Earth.
Pantropy is a hypothetical process of space habitation or space colonization in which, rather than terraforming other planets or building space habitats suitable for human habitation, humans are modified to be able to thrive in the existing environment. The term was coined by science fiction author James Blish, who wrote a series of short stories based on the idea.
"The Big Front Yard" is a science fiction short story by American writer Clifford D. Simak which won a 1959 Hugo Award for Best Novelette. It was also included in The Science Fiction Hall of Fame, Volume Two (1973) after being voted one of the best novellas up to 1965.

Archaeology, Anthropology, and Interstellar Communication is a 2014 collection of essays edited by Douglas Vakoch and published by NASA. The book is focused on the role that the humanities and social sciences, in particular anthropology and archaeology, play in the search for extraterrestrial intelligence (SETI). The seventeen essays are gathered into four sections, which respectively explore the history of SETI as a field; archaeological comparisons for human-alien communication, such as the difficulties of translating ancient languages; the inferential gap between humans and aliens, and the consequences this would have for communication and trade; and the potential nature of alien intelligences.
Pastoral science fiction is a subgenre of science fiction which uses bucolic, rural settings, like other forms of pastoral literature. Since it is a subgenre of science fiction, authors may set stories either on Earth or another habitable planet or moon, sometimes including a terraformed planet or moon. Unlike most genres of science fiction, pastoral science fiction works downplay the role of futuristic technologies. The pioneer is author Clifford Simak (1904–1988), a science fiction Grand Master whose output included stories written in the 1950s and 1960s about rural people who have contact with extraterrestrial beings who hide their alien identity.
