In 1998, David J. Stevenson authored a paper entitled "Possibility of Life Sustaining Planets in Interstellar Space" [1]. In this paper, Stevenson theorizes that wandering planets which drift in the vast expanses of cold interstellar space could possibly sustain a thick atmosphere which would not freeze out due to radiative heat loss. The mechanism he proposes which preserves atmosphere formation in these bodies i ...

Much like "continent", "planet" is a word without a precise definition, with history and culture playing as much of a role as geology and astrophysics. Recent definitions have been vague and imprecise; The American Heritage Dictionary, for instance, formerly defined a planet as: A nonluminous celestial body larger than an asteroid or comet, illuminated by light from a star, such as the Sun, around which it revolves. In the solar system there are nine known planets: Mercury, Venus, Ea ...

A planet is generally considered to be a relatively large mass of accreted matter in orbit around a star that is not a star itself. The name comes from the Greek term πλανήτης, planētēs, meaning "wanderer", as ancient astronomers noted how certain lights moved across the sky in relation to the other stars. Based on historical consensus, the International Astronomical Union (IAU) lists nine planets in our solar system. Since the term "planet" has no precise scientific definition, however, many astronomers contest that ...

Teleportation, or teletransportation, is the process of moving objects from one place to another more or less instantaneously, without using conventional transportation. There are many examples of success in this area. With present techniques, teleportation is conceivable only with elementary particles, or theoretically, by encoding information about an object, transmitting the information to another place, such as on a radio signal, and creating a copy of the original object in the new location. Teleportation has also been proposed to explain various anomalous phenomena, and ...

Betazed is a planet in the fictional television, movie, and book series Star Trek. The Class M planet is populated by a species of telepathic humanoids, the Betazoids. They were first brought into existence on the series when a half Human, half Betazoid character named Deanna Troi was introduced as ship's counselor on the Star Trek: The Next Generation television show. The biennial Trade Agreements Conference, an interstellar congress, was held on Betazed in 2366. Lake Cataria on Betazed was one of Deanna Troi's favorite places. The Janaran Fal ...

The Planetes manga is a 5-part graphic novel series available in English from TOKYOPOP. There are several major differences between the manga and the anime. One change is that the technology in the anime seems to be an improvement over that of the manga, introducing touch-controlled HUDs, retractable debris face shields with a video screen, and peripheral cameras to the EVA suits the main characters use. Also, the anime seems to have improved upon the weightless living and working spaces, with foot and hand bars for people to stabiliz ...

The story of Planetes follows the crew of the DS-12 "Toy Box" of the Space Debris Section, a unit of Technora Corporation, whose task is to prevent the damage or destruction of satellites, space stations and spaceships from debris in Earth's and the Moon's orbit accomplished through a number of methods, most notably the use of EVA suits, where the participants are all licensed to collect debris. The episodes sometimes revolve around debris collection itself, but more often the concept of collecting "trash" in space is me ...

The story of Planetes takes place in the near future. Unlike many other anime and science fiction productions, special care was given in Planetes for a very realistic depiction of space and space travel. For instance, when in a weightless environment, the cel count dramatically increases in order to make weightless motion more fluid and realistic. Also, spaceships make no noise in the vacuum of space and astronauts routinely suffer from known space illnesses such as radiation poisoning, decompression sickness, cancer, brittle b ...

Interstellar travel poses a number of difficulties. There are all the difficulties of interplanetary travel, including hard vacuum, radiation, micrometeoroids, and free fall. These difficulties seem tractable; robot missions have been sent to almost every planet in the Solar system, humans have been sent to the Moon, and manned missions to Mars have been planned for years. Interstellar travel is made enormously more difficult by the million-fold greater distances to nearby stars. Intergalactic travel would involve distances a million-fold greater than interstellar distance ...

Visiting another civilization on a distant world would be fascinating, but at present is beyond human capabilities (see Project Orion and Project Daedalus for some hypothetical explorations of the concept). However, it is perfectly within reach to develop a communications system using a powerful transmitter and a sensitive receiver, and use it to search the sky for extraterrestrial worlds whose citizens have a similar inclination as terrestrials. A basic assumption of SETI is the that of "Mediocrity" [1]: the idea that humanity is not ...

SETI - Early work. In 1960, Cornell University astronomer Frank Drake performed the first modern SETI experiment, named "Project Ozma", after the Queen of Oz in L. Frank Baum's fantasy books. Drake used a 25-meter-diameter radio telescope at Green Bank, West Virginia, to examine the stars Tau Ceti and Epsilon Eridani near the 1.420 gigahertz marker frequency. A 400 kilohertz band was scanned around the marker frequency, using a single-channel receiver with a bandwidth of 100 hertz. The information was stored on tape for off-line ...

While most SETI sky searches have studied the radio spectrum, some SETI researchers have considered the possibility that alien civilizations might be using powerful lasers for interstellar communications at optical wavelengths.
