The Search For Extraterrestrial Intelligence - 1379 Words

The search for extraterrestrial intelligence (SETI) is a collective term for the scientific search for intelligent extraterrestrial life. After Copernicus, Darwin, and Einstein, another incredible revolution in thinking about our place in the universe is taking place, there have been many earlier searches for extraterrestrial intelligence within the Solar System, in accordance with the information obtained in the sources cited in the Reference section. First of all, in 1896, Nikola Tesla suggested that an extreme version of his wireless electrical transmission system could be used to contact beings on Mars, but it was lately proved wrong. Therefore, scientific investigation of the potential phenomenon began shortly after the advent of†¦show more content†¦Therefore, in 1992, the U.S. government funded an operational SETI program, in the form of the NASA Microwave Observing Program (MOP). MOP was planned as a long-term effort to conduct a general survey of the sky and also carry out targeted searches of 800 specific nearby stars. MOP was to be performed by radio antennas associated with the NASA Deep Space Network as well as the 140-foot (43 m) radio telescope of J u a n F r a i l e , 7 t h G r a d e P a g e | 3 the National Radio Astronomy Observatory at Green Bank, West Virginia, and the 1,000- foot (300 m) radio telescope at the Arecibo Observatory in Puerto Rico. But the United States Congress canceled MOP one year after its start. SETI advocates continued without government funding and in 1995 the nonprofit SETI Institute of Mountain View, California, resurrected the MOP program under the name of Project Phoenix, backed by private sources of funding. Project Phoenix, under the direction of Jill Tarter, is a continuation from MOP and studies roughly 1,000 nearby Sun-like stars. From 1995 through March 2004, Phoenix conductedShow MoreRelatedEssay about Intelligent Extraterrestrial Life936 Words   |  4 PagesIntelligent Extraterrestrial Life When I look up at the stars at night, I just have to wonder who or what is looking back at me from some distant planet in some distant galaxy.

Billions of dollars have been spent in research, causing controversy about whether scientists should invest in the hunt for extraterrestrial beings. Due to inadequate technology, humans cannot currently identify whether extraterrestrial life exists, leading to arguments that scientists should refrain from searching for them. Findings on Earth and other planets suggest extraterrestrial life could liveRead MoreAre We Alone?

The main question that interests astronomers is whether there is anyone out there in space. Scientists are trying to search for life that may exist elsewhere in the universe by using instruments and different ways to communicate with extraterrestrial life.

Some astronomers worked on the above question by attempting to estimate the numberRead MoreEssay on The Existence of Intelligent Life1783 Words   |  8 Pagesexistence. Conversely, not finding such a civilization would force us to examine the purpose of our own existence. To help answer the question, astronomers and scientists set up a program in search for extraterrestrial intelligence. This program, or SETI, was set up to verify, by observation that extraterrestrial life does exist. SETI tries to prove this by picking up and analyzing radio signals by means of satellites and advanced computers (Heidmann 116). The history of the SETI program is quiteRead MoreEssay about Possibility of Life on Other Planets1203 Words   |  5 Pageson meteors in space.   For the past fifty years the SETI project, also known as the Search for Extraterrestrial Intelligence, has been broadcasting signals in order to communicate with foreign life-forms (Lemarchand and Lomberg 397).   Everyday there is more of a chance that they will meet their goal as the broadcast signals reach farther and farther into the galaxy.
