Jill Tarter
Jill Cornell Tarter (born January 16, 1944) is an American astronomer best known for her work on the search for extraterrestrial intelligence (SETI). Tarter is the former director of the Center for SETI Research, holding the Bernard M. Oliver Chair for SETI at the SETI Institute. In 2002, '' Discover'' magazine recognized her as one of the 50 most important women in science. Early life and education Tarter grew up in New York State, and graduated from Eastchester High School in 1961. She was elected to its alumni association hall of fame in 2001. Prior to his death when she was twelve years old, Tarter's father was an early inspiration who encouraged her curiosity when she resisted suggestions that she follow pursuits considered more appropriate for a girl and announced that she wanted to be an engineer. On family trips to Florida with her father, she would look up at the dark skies and wonder who or what might be out there. Tarter earned a Bachelor of Engineering Physics degr ...

Radio Astronomy
Radio astronomy is a subfield of astronomy that studies Astronomical object, celestial objects using radio waves. It started in 1933, when Karl Jansky at Bell Telephone Laboratories reported radiation coming from the Milky Way. Subsequent observations have identified a number of different sources of radio emission. These include stars and galaxy, galaxies, as well as entirely new classes of objects, such as Radio galaxy, radio galaxies, quasars, pulsars, and Astrophysical maser, masers. The discovery of the cosmic microwave background radiation, regarded as evidence for the Big Bang, Big Bang theory, was made through radio astronomy. Radio astronomy is conducted using large Antenna (radio), radio antennas referred to as ''radio telescopes'', that are either used alone, or with multiple linked telescopes utilizing the techniques of Astronomical interferometer, radio interferometry and aperture synthesis. The use of interferometry allows radio astronomy to achieve high angular resolu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Dwarf
Brown dwarfs are substellar objects that have more mass than the biggest gas giant planets, but less than the least massive main sequence, main-sequence stars. Their mass is approximately 13 to 80 Jupiter mass, times that of Jupiter ()not big enough to sustain nuclear fusion of hydrogen into helium in their cores, but massive enough to emit some light and heat from the deuterium fusion, fusion of deuterium (deuterium, 2H). The most massive ones (> ) can lithium burning, fuse lithium (lithium-7, 7Li). Astronomers classify self-luminous objects by Stellar classification#Spectral types, spectral type, a distinction intimately tied to the surface temperature, and brown dwarfs occupy types M (2100–3500 Kelvin, K), L (1300–2100 Kelvin, K), T (600–1300 Kelvin, K), and Y ( 80 ''M''J), which have spectral classes L2 to L6. Spectral class T As GD 165B is the prototype of the L dwarfs, Gliese 229B is the prototype of a second ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Margaret Turnbull
Margaret Carol "Maggie" Turnbull (born 1975) is an American astronomer and astrobiologist. She received her PhD in Astronomy from the University of Arizona in 2004. Between 2001 and 2006 she was a part of the Virtual Planetary Laboratory. Turnbull is an authority on star systems which may have habitable planets, solar twins and planetary habitability. She is also an expert on the use of the coronagraph in the direct detection of exoplanets. In 2002, Turnbull developed the HabCat along with Jill Tarter, a catalog of potentially habitable stellar systems. The following year Turnbull went on to further identify 30 particularly suitable stars from the 5,000 in the HabCat list that are within 100 light years of Earth. In 2006, Turnbull drew up two shortlists of just five stars each. The first formed the basis of SETI radio searches with the Allen Telescope Array (Beta Canum Venaticorum, HD 10307, HD 211415, 18 Scorpii, and 51 Pegasi). The second are her top candidates for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Project Phoenix (SETI)
Project Phoenix was a SETI project to search for extraterrestrial intelligence by analyzing patterns in radio signals. It was run by the independently funded SETI Institute of Mountain View, California, U.S. Project Phoenix started work in February 1995 with the Parkes radio telescope located in New South Wales, Australia, the largest telescope in the Southern Hemisphere. Between September 1996 and April 1998, the Project used the National Radio Astronomy Observatory, Green Bank in Green Bank, West Virginia, U.S. Rather than attempting to scan the whole sky for messages, the Project concentrated on nearby systems that are similar to our own. Project Phoenix's targets comprised about 800 stars with a 200 light-year range. The Project searched for radio signals as narrow as 1 Hz between 1,000 and 3,000 MHz: a broad bandwidth compared with most SETI searches. In March 2004 the Project announced that after checking the 800 stars on its list, it had failed to find any ev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High Resolution Microwave Survey
The High Resolution Microwave Survey (HRMS) was a NASA project that was to scan ten million frequencies using radio telescopes. A decade in the making, the objective was to find transmissions from alien intelligences. The primary point of observation for the project was the Arecibo Ionospheric Observatory in Puerto Rico. The project began in October 1992 with SETI researcher Jill Tarter on board. However, one year later, first-term Nevada Senator Richard Bryan Richard Hudson Bryan (born July 16, 1937) is an American retired politician and attorney who served as the 25th Governor of Nevada from 1983 to 1989 and as a United States Senator representing Nevada from 1989 until 2001. A Democrat, Bryan pr ... was responsible for removing funding for the project.

Backronym
A backronym is an acronym formed from an already existing word by expanding its letters into the words of a phrase. Backronyms may be invented with either serious or humorous intent, or they may be a type of false etymology or folk etymology. The word is a portmanteau of ''back'' and ''acronym''. A normal acronym is a word derived from the initial letter(s) of the words of a phrase, such as ''radar'' from "radio detection and ranging". By contrast, a backronym is "an acronym deliberately formed from a phrase whose initial letters spell out a particular word or words, either to create a memorable name or as a fanciful explanation of a word's origin". Many list of fictional espionage organizations, fictional espionage organizations are backronyms, such as SPECTRE (special executive for counterintelligence, terrorism, revenge and extortion) from the ''James Bond'' franchise. For example, the Amber Alert missing-child program was named after Amber Hagerman, a nine-year-old girl w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SERENDIP
SERENDIP (Search for Extraterrestrial Radio Emissions from Nearby Developed Intelligent Populations) is a Search for Extra-Terrestrial Intelligence (SETI) program originated by the Berkeley SETI Research Center at the University of California, Berkeley. SERENDIP takes advantage of ongoing "mainstream" radio telescope observations as a " piggy-back" or "commensal" program. Rather than having its own observation program, SERENDIP analyzes deep space radio telescope data that it obtains while other astronomers are using the telescope. Background The initial SERENDIP instrument was a 100-channel analog radio spectrometer covering 100 kHz of bandwidth. Subsequent instruments have been significantly more capable, with the number of channels doubling roughly every year. These instruments have been deployed at a large number of telescopes including the NRAO 90m telescope at the Green Bank Observatory and the Arecibo 305m telescope. SERENDIP observations have been conducted at f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PDP-8
The PDP-8 is a family of 12-bit minicomputers that was produced by Digital Equipment Corporation (DEC). It was the first commercially successful minicomputer, with over 50,000 units sold during the model's lifetime. Its basic design follows the pioneering LINC but has a smaller instruction set, which is an expanded version of the PDP-5 instruction set. Similar machines from DEC are the PDP-12 which is a modernized version of the PDP-8 and LINC concepts, and the PDP-14 industrial controller system. Overview The earliest PDP-8 model, informally known as a "Straight-8", was introduced on 22 March 1965 priced at $18,500 (). It uses diode–transistor logic packaged on flip chip cards in a machine about the size of a small household refrigerator. It was the first computer to be sold for under $20,000, making it the best-selling computer in history at that time. The Straight-8 was supplanted in 1966 by the PDP-8/S, which was available in desktop and rack-mount models. Using a on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Stuart Bowyer
Charles Stuart Bowyer (August 2, 1934 – September 23, 2020) was an American astronomer and academic. He was a professor at the University of California. Early life and education Bowyer was born in Toledo, Ohio, to Howard and Elizabeth Bowyer. His father was a pilot. As a boy, he attended a one-room grade school near his father’s farm in Orland Park, Ill., before being valedictorian at Orland Park High School. He graduated from Miami University of Ohio with a degree in physics. He received his Ph.D. in physics from Catholic University in 1965. Career Bowyer was a professor at University of California at Berkeley. He was also affiliated with the United States Naval Research Laboratory. He worked in a group directed by Herbert Friedman. He is generally given credit for starting the field of extreme ultraviolet astronomy. Bowyer’s pursuit of studying ultraviolet rays was met with resistance at first - astronomers argued that even outside of the Earth's atmosphere most ultraviol ...

Project Cyclops
Project Cyclops is a 1971 NASA project that investigated how the search for extraterrestrial intelligence (SETI) should be conducted. As a NASA product the report is in the public domain. The project team created a design for coordinating large numbers of radio telescopes to search for Earth-like radio signals at a distance of up to 1,000 light-years to find intelligent life. The proposed design involving between 1,000 and 2,500 steerable dishes of 100m diameter each was shelved due to costs. However, the report became the basis for much of the SETI work to follow. The approach NASA devised for SETI was to develop a framework with the present understanding of the universe, and then use that as the basis for increasing the probability of discovering extraterrestrials. Making no assumptions, apart from that extraterrestrial radio signals exist, it focused on scanning the skies for signals that could indicate the presence of intelligent life forms. Original conclusions The main c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
