One of the most common unanswered questions scientists find themselves asking is "Is there life on other planets?" Since the first famously documented UFO sighting in 1947, the idea of extra-terrestrial life has been debated almost non-stop. The subject has inspired many TV programs, such as The X-Files, and films (Mars Attacks, Independence Day, and the Men in Black films to name but a few). Scientists have come up with many new ideas and ways of trying to either prove or disprove the existence of life elsewhere.

Mars is a very similar planet to earth in relation to size and atmosphere. Therefore it seemed like the most likely place to search for life. At the end of the 19th century, an American named Percival Lowell built himself an

The SETI project has been using radio telescopes since the 60's, but has had no positive results yet.
The SETI project began in 1959 when Philip Morrison and Giuseppe Coconni publish in Nature magazine the first modern SETI article, "Searching for Interstellar Communication," which first illustrated the potential of using microwave radio for extraterrestrial communication. In 1960 Dr. Frank Drake conducted the first SETI search, Project Ozma. In 1961 the first SETI conference, Order of the Dolphin, is held at the National Radio Astronomy Observatory in Green Bank, WV. Dr. Drake introduces as its agenda what is now know as the Drake Equation, a controversial statistical method for estimating the number of advanced technological civilizations in the Milky Way Galaxy. In 1982 NASA began SETI searches with The High Resolution Microwave Survey (HRMS). 1988 saw The Planetary Society organize an international meeting on SETI in Toronto, Canada. This led to a Robert Stephens establishing project TARGET (Telescope Antenna Researching Galactic Extraterrestrial Transmissions). In 1999 SETI@home, a new screen saver program that taps into the power of home computers, was launched. It has the potential of radically changing SETI program design in the future of extra-terrestrial searches.

With all of this scientific research, it is no wonder that many people
