List of Alien characters
"Alien", a science-fiction action horror franchise, tells the story of humanity's ongoing encounters with Aliens: a hostile, endoparasitoid, extraterrestrial species. Set between the 21st and 24th centuries over several generations, the film series centers around a character ensemble's struggle for survival against the Aliens and against the greedy, unscrupulous megacorporation Weyland-Yutani. The main series consists of four films, "Alien" (1979), "Aliens" (1986), "Alien 3" (1992) and "Alien Resurrection" (1997), about Ellen Ripley's fight against the Aliens. Ripley is the sole survivor of an Alien rampage on the space freighter "Nostromo", which leads her to a series of conflicts with the species and Weyland-Yutani.
Extraterrestrial life
Extraterrestrial life, also called alien life (or, if it is a sentient or relatively complex individual, an "extraterrestrial" or "alien"), is life that occurs outside of Earth and that probably did not originate from Earth. These hypothetical life forms may range from simple prokaryotes to beings with civilizations far more advanced than humanity. The Drake equation speculates about the existence of intelligent life elsewhere in the universe. The science of extraterrestrial life in all its forms is known as exobiology. Since the mid-20th century, there has been an ongoing search for signs of extraterrestrial life.
List of Ben 10 villains
Below is a list of all the villains who appear in the "Ben 10" universe ranging from "Ben 10", "", "", "", and "Ben 10 (Reboot)". Each of the villains has been sorted into the TV series that he or she debuted in. Voiced by: Vilgax is a warlord who is Ben's first and most recurring nemesis through the series. Being of the Chimera Sui Generis (named after the mythological Chimera) race, who are able to turn into giant squid-like creatures when exposed to water, Vilgax was exiled from his home world for being ruthless, cruel, and power hungry. Soon after, Vilgax meets Maltruant as depicted in the Omniverse series finale which had him indirectly learn of the Omnitrix's existence when attacked by George Washington and a mysterious figure later revealed to be Ben.
Fermi paradox
The Fermi paradox or Fermi's paradox, named after physicist Enrico Fermi, is the apparent contradiction between the lack of evidence and high probability estimates for the existence of extraterrestrial civilizations. The basic points of the argument, made by physicists Enrico Fermi (1901–1954) and Michael H. Hart (born 1932), are: According to this line of reasoning, the Earth should have already been visited by extraterrestrial aliens. In an informal conversation, Fermi noted no convincing evidence of this, leading him to ask, "Where is everybody?" There have been many attempts to explain the Fermi paradox, primarily either suggesting that intelligent extraterrestrial life is extremely rare or proposing reasons that such civilizations have not contacted or visited Earth.
Alien (franchise)
Alien is an American science-fiction horror media franchise centered on the film series depicting Warrant Officer Ellen Ripley (played by Sigourney Weaver) and her battles with an extraterrestrial lifeform, commonly referred to as "the Alien", and depicting android David 8 (portrayed by Michael Fassbender) and his experimentation in creating said lifeform. Produced and distributed by 20th Century Fox, the series began with "Alien" (1979), directed by Ridley Scott. It was followed by three sequels, "Aliens" (1986), "Alien 3" (1992), and "Alien Resurrection" (1997). Scott also directed a prequel series, composed of "Prometheus" (2012) and "" (2017).
List of Ben 10 characters
This is a list of characters in the universe of Cartoon Network's "Ben 10" franchise, which includes "Ben 10", "", "", "", and "Ben 10 (Reboot)". Voiced by:  Portrayed by:  Benjamin Kirby "Ben" Tennyson (alias "Ben 10") is the main character of the franchise. He is a 10-year-old boy child from Bellwood who found the Omnitrix during his summer vacation with his Grandfather Max Tennyson and his cousin Gwen Tennyson. The Omnitrix attached to his wrist and gives him the powers and abilities to become different aliens. He uses these powers to defeat evil while trying to escape the alien warlord Vilgax, who chases after him unstoppably in order to retrieve the Omnitrix.
List of Alien morphs in the Alien franchise
The Alien franchise features several morphs of the Alien life form. This includes different castes, hybrids, mutants, and genetically engineered forms, which are listed below. Aliens are depicted as eusocial life-forms with a defined caste system which is ruled by a queen. Their life cycle comprises several distinct stages: they begin their lives as an egg, which hatches a parasitic larval form known as a facehugger, which then attaches itself to a living host by latching onto its face. The facehugger then "impregnates" the host with an embryo known as a chestburster, which, after a gestation period of several hours, erupts violently from the host's chest resulting in the death of the host.

Drake equation
The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy. The number of such civilizations , is assumed to be equal to the mathematical product of  for a combined expression of: The equation was written in 1961 by Frank Drake, not for purposes of quantifying the number of civilizations, but as a way to stimulate scientific dialogue at the first scientific meeting on the search for extraterrestrial intelligence (SETI). The equation summarizes the main concepts which scientists must contemplate when considering the question of other radio-communicative life.

Rare Earth hypothesis
In planetary astronomy and astrobiology, the Rare Earth Hypothesis argues that the origin of life and the evolution of biological complexity such as sexually reproducing, multicellular organisms on Earth (and, subsequently, human intelligence) required an improbable combination of astrophysical and geological events and circumstances. According to the hypothesis, complex extraterrestrial life is a very improbable phenomenon and likely to be extremely rare. The term "Rare Earth" originates from "Rare Earth: Why Complex Life Is Uncommon in the Universe" (2000), a book by Peter Ward, a geologist and paleontologist, and Donald E. Brownlee, an astronomer and astrobiologist, both faculty members at the University of Washington.
Astrobiology
Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe: extraterrestrial life and life on Earth. Astrobiology addresses the question of whether life exists beyond Earth, and how humans can detect it if it does. The term exobiology is similar but more specific—it covers the search for life beyond Earth, and the effects of extraterrestrial environments on living things. Astrobiology makes use of physics, chemistry, astronomy, biology, molecular biology, ecology, planetary science, geography, and geology to investigate the possibility of life on other worlds and help recognize biospheres that might be different from that on Earth.
Circumstellar habitable zone
In astronomy and astrobiology, the circumstellar habitable zone (CHZ), or simply the habitable zone, is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure. The bounds of the CHZ are based on Earth's position in the Solar System and the amount of radiant energy it receives from the Sun. Due to the importance of liquid water to Earth's biosphere, the nature of the CHZ and the objects within it may be instrumental in determining the scope and distribution of Earth-like extraterrestrial life and intelligence. The habitable zone is also called the Goldilocks zone, a metaphor of the children's fairy tale of "Goldilocks and the Three Bears", in which a little girl chooses from sets of three items, ignoring the ones that are too extreme (large or small, hot or cold, etc.
String theory
In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. It describes how these strings propagate through space and interact with each other. On distance scales larger than the string scale, a string looks just like an ordinary particle, with its mass, charge, and other properties determined by the vibrational state of the string. In string theory, one of the many vibrational states of the string corresponds to the graviton, a quantum mechanical particle that carries gravitational force. Thus string theory is a theory of quantum gravity.

Milky Way
The Milky Way is the galaxy that contains our Solar System. The descriptive "milky" is derived from the appearance from Earth of the galaxy – a band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye. The term "Milky Way" is a translation of the Latin ', from the Greek (', "milky circle"). From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s, most astronomers thought that the Milky Way contained all the stars in the Universe.

Stargate (device)
A Stargate is an Einstein–Rosen bridge portal device within the "Stargate" fictional universe that allows practical, rapid travel between two distant locations. The devices first appear in the 1994 Roland Emmerich film "Stargate", and thereafter in the television series "Stargate SG-1", "Stargate Atlantis", and "Stargate Universe". In these productions the Stargate functions as a plot generator, allowing the main characters to visit alien planets without the need for spaceships or any other type of technology. The device allows for near-instantaneous travel across both interstellar and extragalactic distances.
Mythology of Stargate
In the fictional universe of the "Stargate" franchise, the people of Earth have encountered numerous extraterrestrial races on their travels through the Stargate. In addition to a diversity of alien life, there is also an abundance of other humans, scattered across the cosmos by advanced aliens in the distant past. Some of the most significant species in "Stargate SG-1" are the Goa'uld, the Asgard, and the Replicators. "Stargate Atlantis", set in the Pegasus galaxy, introduced the Wraith and the Asurans. One of the most influential species in "Stargate", the Ancients, have moved on to a higher plane of existence.

Galaxy
A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The word galaxy is derived from the Greek "" (), literally "milky", a reference to the Milky Way. Galaxies range in size from dwarfs with just a few hundred million () stars to giants with one hundred trillion () stars, each orbiting its galaxy's center of mass. Galaxies are categorized according to their visual morphology as elliptical, spiral, or irregular. Many galaxies are thought to have black holes at their active centers. The Milky Way's central black hole, known as Sagittarius A*, has a mass four million times greater than the Sun.
Andromeda Galaxy
The Andromeda Galaxy (), also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 780 kiloparsecs (2.5 million light-years) from Earth, and the nearest major galaxy to the Milky Way. Its name stems from the area of the sky in which it appears, the constellation of Andromeda. The 2006 observations by the Spitzer Space Telescope revealed that the Andromeda Galaxy contains approximately one trillion stars, more than twice the number of the Milky Way’s estimated 200-400 billion stars. The Andromeda Galaxy, spanning approximately 220,000 light years, is the largest galaxy in our Local Group, which is also home to the Triangulum Galaxy and other minor galaxies.
Globular cluster
A globular cluster is a spherical collection of stars that orbits a galactic core as a satellite. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and relatively high stellar densities toward their centers. The name of this category of star cluster is derived from the Latin "globulus"—a small sphere. A globular cluster is sometimes known more simply as a "globular". Globular clusters are found in the halo of a galaxy and contain considerably more stars and are much older than the less dense open clusters, which are found in the disk of a galaxy. Globular clusters are fairly common; there are about 150 to 158 currently known globular clusters in the Milky Way, with perhaps 10 to 20 more still undiscovered.
Eridanus II
The Eridanus II Dwarf is a low-surface brightness dwarf galaxy in the constellation Eridanus. Eridanus II was independently discovered by two groups in 2015, using data from the Dark Energy Survey (Bechtol et al., 2015; Koposov et al. 2015). This galaxy is probably a distant satellite of the Milky Way. Li et al., 2016. Eridanus II contains a centrally located globular cluster; and is the smallest, least luminous galaxy known to contain a globular cluster. Crnojević et al., 2016. Eridanus II is significant, in a general sense, because the widely accepted Lambda CDM cosmology predicts the existence of many more dwarf galaxies than have yet been observed.

High-velocity cloud
High-velocity clouds (HVCs) are large collections of gas found throughout the galactic halo of the Milky Way. Their bulk motions in the local standard of rest have velocities which are measured in excess of 70–90 km s. These clouds of gas can be massive in size, some on the order of millions of times the mass of the Sun (formula_1), and cover large portions of the sky. They have been observed in the Milky Way's halo and within other nearby galaxies. HVCs are important to the understanding of galactic evolution because they account for a large amount of baryonic matter in the galactic halo. In addition, as these clouds fall into the disk of the galaxy, they add material that can form stars in addition to the dilute star forming material already present in the disk.

Ancient (Stargate)
The Ancients (in their own tongue "Anquietas") are a fictional humanoid race in the "Stargate" franchise. They are called by this name in the Milky Way galaxy, and the Ancestors and Lanteans in the Pegasus galaxy. The Ancients are one of two groups of the Alterans; the other being the Ori, the main antagonists in the later seasons of "Stargate SG-1". In the "Stargate" universe, the Ancients are one of the most technologically advanced species known to have existed. The Ancients evolved tens of millions of years ago and reached advanced level of technology long before humans evolved on Earth. They lived in the Milky Way and Pegasus galaxies prior to their ascension.

Milky Way (chocolate bar)
The Milky Way bar is a chocolate-covered candy bar manufactured and distributed by the Mars confectionery company. The American version of the Milky Way bar is made of chocolate-malt nougat topped with caramel and covered with milk chocolate and sold as the Mars bar everywhere else. The global Milky Way is a different chocolate candy bar similar to the American 3 Musketeers. The Milky Way bar was created in 1923 by Frank C. Mars and originally manufactured in Minneapolis, Minnesota. The name and taste were taken from a famed malted milk drink (milkshake) of the day, which was in turn named after the Earth’s galaxy.
