Class M Planet
In the '' Star Trek'' universe, a Class M planet is one habitable by humans and similar life forms. Earth, Vulcan, Romulus, and Qo'noS are examples of Class M planets. The planet needs an atmosphere of oxygen and nitrogen, should be close to a stable star, have fertile soil, a tolerable gravity, a climate that is generally pleasant for humans. Most planets shown in the franchise are Class M planets; occasionally another alphabetically named class of planet is shown, each hostile to humanoid life in one or more ways. As a story device, this allowed for easy filming without restriction by environmental suits, but ''Science'' correspondent Gretchen Vogel called it a "failure of imagination" when thinking about the limits of the zone capable of supporting life. The origin within the fictional universe is implied to be the Vulcan word ''Minshara''. See also * Earth in science fiction An overwhelming majority of fiction is set on or features the Earth.

Star Trek
''Star Trek'' is an American science fiction media franchise created by Gene Roddenberry, which began with the eponymous 1960s television series and quickly became a worldwide pop-culture phenomenon.

It was first broadcast on September 6, 1966 on Canada's CTV network. It followed the voyages of the crew of the starship USS ''Enterprise'', a space exploration vessel built by the United Federation of Planets in the 23rd century, on a mission "to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before".

Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulcan (Star Trek)
Vulcans, sometimes referred to as Vulcanians, are a fictional extraterrestrial humanoid species in the ''Star Trek'' universe and media franchise. In the various ''Star Trek'' television series and films, they are noted for their attempt to live by logic and reason with as little interference from emotion as possible. Known for their pronounced eyebrows and pointed ears, they originate from the fictional planet Vulcan. In the ''Star Trek'' universe, they were the first extraterrestrial species to make contact with humans. The most notable portrayal of a Vulcan is by actor Leonard Nimoy, who first played the character Mr. Spock (picture shown at right) in '' Star Trek: The Original Series'' (1966–1969). "Pointy ears", the " Vulcan salute" (hand gesture) and the "Vulcan nerve pinch" are aspects of this fictional race that have entered popular culture. Development The Vulcan, Spock, first appeared in the original 1965 ''Star Trek'' pilot, " The Cage", shown to studio execu ...

Romulan
The Romulans () are an extraterrestrial race in the American science fiction franchise ''Star Trek''. They first appeared in the series ''Star Trek'' (1966–1969). They have appeared in most subsequent ''Star Trek'' releases, including '' The Animated Series'', ''The Next Generation'', ''Deep Space Nine'', '' Voyager'', ''Enterprise'', ''Discovery'', '' Picard'', '' Strange New Worlds'', and '' Lower Decks''. They appear in the ''Star Trek'' feature films '' Star Trek V: The Final Frontier'' (1989), '' Star Trek VI: The Undiscovered Country'' (1991), '' Star Trek: Nemesis'' (2002) and ''Star Trek'' (2009). They also appear in various other spin-off media, including books, comics, toys and games. Writer Paul Schneider created the Romulans for the 1966 ''Star Trek'' episode " Balance of Terror". As a basis, he considered what the ancient Roman Empire might have looked like had it developed to the point of spaceflight. Physically, the Romulans were presented as humanoid, but the s ...

Klingon
The Klingons ( ; Klingon: ''tlhIngan'' ) are a fictional species in the science fiction franchise ''Star Trek''. Developed by screenwriter Gene L. Coon in 1967 for the original ''Star Trek'' (''TOS'') series, Klingons were swarthy humanoids characterized by prideful ruthlessness and brutality. Klingons practiced feudalism and authoritarianism, with a warrior caste relying on slave labor. With a greatly expanded budget for makeup and effects, the Klingons were completely redesigned for '' Star Trek: The Motion Picture'' (1979), acquiring ridged foreheads. In subsequent television series and in later films, the militaristic traits of the Klingons were bolstered by an increased sense of honor and strict warrior code similar to those of bushido. Klingons are recurring antagonists in the 1960s television series ''Star Trek'', and have appeared in all subsequent series, along with ten of the ''Star Trek'' feature films. Initially intended to be antagonists for the crew of the USS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Geographic
''National Geographic'' (formerly the ''National Geographic Magazine'', sometimes branded as NAT GEO) is a popular American monthly magazine published by National Geographic Partners. Known for its photojournalism, it is one of the most widely read magazines of all time. The magazine was founded in 1888 as a scholarly journal, nine months after the establishment of the society, but is now a popular magazine. In 1905, it began including pictures, a style for which it became well-known. Its first color photos appeared in the 1910s. During the Cold War, the magazine committed itself to present a balanced view of the physical and human geography of countries beyond the Iron Curtain. Later, the magazine became outspoken on environmental issues. Since 2019, controlling interest has been held by The Walt Disney Company. Topics of features generally concern geography, history, nature, science, and world culture. The magazine is well known for its distinctive appearance: a thick squa ...

Science (journal)
''Science'', also widely referred to as ''Science Magazine'', is the peer-reviewed academic journal of the American Association for the Advancement of Science (AAAS) and one of the world's top academic journals.

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.J. F. Kasting, D. P. Whitmire, R. T. Reynolds, Icarus 101, 108 (1993). 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 planets capable of supporting Earth-like extraterrestrial life and intelligence. The habitable zone is also called the Goldilocks zone, a metaphor, allusion and antonomasia 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.), and set ...

Earth In Science Fiction
An overwhelming majority of fiction is set on or features the Earth. This also holds true of science fiction, despite perceptions to the contrary. Counterfactual depictions of the shape of the Earth, be it flat or hollow, occasionally are featured. A personified, living Earth appears in a handful of works. In works set in the far future, Earth can be a center of space-faring human civilization, or just one of many inhabited planets of a galactic empire, and sometimes destroyed by ecological disaster or nuclear war or otherwise forgotten or lost. Related vocabulary In a number of works of science fiction, Earth's English name has become less popular, and the planet is instead known as Terra or Tellus, Latin words for Earth. Inhabitants of Earth can be referred to as Earthlings, Earthers, Earthborn, Earthfolk, Earthians, Earthies (this term being often seen as derogatory), Earthmen (and Earthwomen), Earthpersons, Earthsiders, Solarians, Tellurians, Terrestrials, Terrestrians, or ...
