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. [1] [2] [3] In 2002, Discover magazine recognized her as one of the 50 most important women in science. [4]
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. [5] 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. [6] [7]
Tarter earned a Bachelor of Engineering Physics degree as an undergraduate at Cornell University (1965) as the only woman in her graduating class of 300 in the engineering college. Her professional interest in astronomy emerged as she pursued a Master's degree (1971) and PhD (1975) at the University of California at Berkeley. [6] [7] [8] In her PhD dissertation, she coined the term "brown dwarf" while researching small-mass objects that fail to stably fuse hydrogen. [9]
Tarter has worked on a number of major scientific projects, most relating to the search for extraterrestrial life. As a graduate student, she was inspired to do SETI research by the Cyclops Report. Stuart Bowyer gave her the report to read when Bowyer discovered that Tarter could program the then-outdated PDP-8/S computer that had been donated by Jack Welch for Bowyer's SETI a project at Hat Creek Radio Observatory. She worked with Bowyer on the radio-search project SERENDIP and created the corresponding backronym, "Search for Extraterrestrial Radio Emissions from Nearby Developed Intelligent Populations". [6] She was project scientist for NASA's High Resolution Microwave Survey (HRMS) in 1992 and 1993 and subsequently director of Project Phoenix (HRMS reconfigured) under the auspices of the SETI Institute. She was co-creator with Margaret Turnbull of the HabCat in 2002, a principal component of Project Phoenix. Tarter has published dozens of technical papers and lectures extensively both on the search for extraterrestrial intelligence and the need for proper science education. She had spent 35 years in the quest for extraterrestrial life when she announced her retirement in 2012. [2] [3] [10]
On October 20, 2006, Tarter appeared on the Point of Inquiry podcast to discuss the question: "Are we alone?" Tarter stated, "Humans will have a different view about being human if and when we know the answer to the 'Are we alone?' question." [11]
In 2011, Tarter delivered a talk, "Intelligent Life in the Universe: Is Anybody Out There?", at the first Starmus Festival in the Canary Islands. The Festival, founded by astronomer Garik Israelian, was a blend of astronomy, allied sciences, music, and art. Tarter subsequently joined the Starmus Board of Directors, along with Israelian, astrophysicist and Queen founding guitarist Brian May, theoretical physicist Stephen Hawking, evolutionary biologist Richard Dawkins, and others. Her 2011 talk was published in the book Starmus: 50 Years of Man in Space. [12] Tarter is a member of the CuriosityStream Advisory Board and the Space for Humanity Board of Advisors. [13]
In May 2013, the Science Laureates of the United States Act of 2013 was introduced into Congress. Tarter was listed by one commentator as a possible nominee for the position of Science Laureate, if the act were to pass. [14]
In 2017, science journalist Sarah Scoles published a biography of Tarter and a history of SETI, called Making Contact: Jill Tarter and the Search for Extraterrestrial Intelligence. [15]
Tarter's work in astrobiology and her success as a female scientist have garnered achievement awards from a number of scientific organizations.
Tarter's astronomical work is illustrated in Carl Sagan's novel Contact . In the film version of Contact, the protagonist Ellie Arroway is played by Jodie Foster. Tarter conversed with the actress for months before and during filming, and Arroway was "largely based" on Tarter's work. [26] She has also been featured in John Boswell's Symphony of Science music video, "The Poetry of Reality (An Anthem for Science)". [27]
Prior to Seticon II in 2012 Tarter addressed concerns about alien invasion, like those seen in science fiction films, in particular those expressed by Stephen Hawking. Correlated with Hawking's reservations is his belief that humans should not attempt to broadcast signals in order to contact alien civilizations (Active SETI). Tarter thinks that aliens evolved enough to communicate with and travel to Earth will be long-lived enough to have needed to grow beyond violent tendencies. [28] [29]
The Fermi paradox is the discrepancy between the lack of conclusive evidence of advanced extraterrestrial life and the apparently high likelihood of its existence. Those affirming the paradox generally conclude that if the conditions required for life to arise from non-living matter are as permissive as the available evidence on Earth indicates, then extraterrestrial life would be sufficiently common such that it would be implausible for it not to have been detected yet.
The search for extraterrestrial intelligence (SETI) is a collective term for scientific searches for intelligent extraterrestrial life. Methods include monitoring electromagnetic radiation for signs of transmissions from civilizations on other planets, optical observation, and the search for physical artifacts. Attempts to message extraterrestrial intelligences have also been made.
Frank Donald Drake was an American astrophysicist and astrobiologist.
Contact is a 1985 hard science fiction novel by American scientist Carl Sagan. It deals with the theme of contact between humanity and a more technologically advanced extraterrestrial life form. It ranked No. 7 on Publishers Weekly's 1985 bestseller list. The only full work of fiction published by Sagan, the novel originated as a screenplay by Sagan and Ann Druyan in 1979; when development of the film stalled, Sagan decided to convert the stalled film into a novel. The film concept was subsequently revived and eventually released in 1997 as the film Contact starring Jodie Foster.
Extraterrestrial intelligence (ETI) refers to hypothetical intelligent extraterrestrial life. No such life has ever been verifiably observed to exist. The question of whether other inhabited worlds might exist has been debated since ancient times. The modern form of the concept emerged when the Copernican Revolution demonstrated that the Earth was a planet revolving around the Sun, and other planets were, conversely, other worlds. The question of whether other inhabited planets or moons exist was a natural consequence of this new understanding. It has become one of the most speculative questions in science and is a central theme of science fiction and popular culture.
Contact is a 1997 American science fiction drama film in Panavision co-produced and directed by Robert Zemeckis, based on the 1985 novel of the same name by Carl Sagan. Sagan and his wife Ann Druyan wrote the story outline for the film. It stars Jodie Foster as Dr. Eleanor "Ellie" Arroway, a SETI scientist who finds evidence of extraterrestrial life and is chosen to make first contact. It also stars Matthew McConaughey, James Woods, Tom Skerritt, William Fichtner, John Hurt, Angela Bassett, Rob Lowe, Jake Busey, and David Morse. It features the Very Large Array in New Mexico, the Arecibo Observatory in Puerto Rico, the Mir space station, and the Space Coast surrounding Cape Canaveral.
The SETI Institute is a not-for-profit research organization incorporated in 1984 whose mission is to explore, understand, and explain the origin and nature of life in the universe, and to use this knowledge to inspire and guide present and future generations, sharing knowledge with the public, the press, and the government. SETI stands for the "search for extraterrestrial intelligence".
Xenoarchaeology, a branch of xenology dealing with extraterrestrial cultures, is a hypothetical form of archaeology that exists mainly in works of science fiction. The field is concerned with the study of the material remains to reconstruct and interpret past life-ways of alien civilizations. Xenoarchaeology is not currently practiced by mainstream archaeologists due to the current lack of any material for the discipline to study.
The communication with extraterrestrial intelligence (CETI) is a branch of the search for extraterrestrial intelligence (SETI) that focuses on composing and deciphering interstellar messages that theoretically could be understood by another technological civilization. The best-known CETI experiment of its kind was the 1974 Arecibo message composed by Frank Drake.
Active SETI is the attempt to send messages to intelligent extraterrestrial life. Active SETI messages are predominantly sent in the form of radio signals. Physical messages like that of the Pioneer plaque may also be considered an active SETI message. Active SETI is also known as METI.
Garik Israelian is an Armenian-Spanish astrophysicist and co-founder of the Starmus Festival. In 1999, Israelian and colleagues presented the first observational evidence that supernova explosions were responsible for the formation of stellar-mass black holes.
The cultural impact of extraterrestrial contact is the corpus of changes to terrestrial science, technology, religion, politics, and ecosystems resulting from contact with an extraterrestrial civilization. This concept is closely related to the search for extraterrestrial intelligence (SETI), which attempts to locate intelligent life as opposed to analyzing the implications of contact with that life.
"Message from space" is a type of "first contact" theme in science fiction. Stories of this type involve receiving an interstellar message which reveals the existence of other intelligent life in the universe.
Alien Encounters is a science fiction mini series on the Science Channel. The series explores how humanity might react to first-contact with aliens. The fictional series is presented as a documentary intermixed with commentary from scientists and sci-fi writers. The series begins with an alien signal detected by the SETI Institute and follows through alien contact and the creation of hybrids ("Brids") based on alien DNA.
Breakthrough Initiatives is a science-based program founded in 2015 and funded by Julia and Yuri Milner, also of Breakthrough Prize, to search for extraterrestrial intelligence over a span of at least 10 years. The program is divided into multiple projects. Breakthrough Listen will comprise an effort to search over 1,000,000 stars for artificial radio or laser signals. A parallel project called Breakthrough Message is an effort to create a message "representative of humanity and planet Earth". The project Breakthrough Starshot, co-founded with Mark Zuckerberg, aims to send a swarm of probes to the nearest star at about 20% the speed of light. The project Breakthrough Watch aims to identify and characterize Earth-sized, rocky planets around Alpha Centauri and other stars within 20 light years of Earth. Breakthrough plans to send a mission to Saturn's moon Enceladus, in search for life in its warm ocean, and in 2018 signed a partnership agreement with NASA for the project.
The Carl Sagan Prize for Science Popularization is an annual $5,000 award presented in honor of the late scientist Carl Sagan by Wonderfest, the San Francisco Bay Area Beacon of Science, to a scientist who has "contributed mightily to the public understanding and appreciation of science."
The Berkeley SETI Research Center (BSRC) conducts experiments searching for optical and electromagnetic transmissions from intelligent extraterrestrial civilizations. The center is based at the University of California, Berkeley.
METI International, known simply as METI, is a non-profit research organization founded in July 2015 by Douglas Vakoch that creates and transmits interstellar messages to attempt to communicate with extraterrestrial civilizations. It is based in San Francisco, California.
