The article "Our Mission" explains what the SETI Institute is set out to do. It was founded in 1984 and now over 150 scientists work for this non-profit organization. The SETI has three different headquarters called the Center for SETI Research, the Carl Sagan Center for the Study of Life in the Universe, and the Center for Education and Public Outreach. Its sole purpose is to understand the origin of life and the possibility of life on other planets.

11th & 12th SETI Articles
"The Allen Telescope Array" is an article explaining what the Allen Telescope Array (ATA) is and its purpose. In 2001, 42 antennas were built and in October 2007 the ATA started its observations. The ATA is a large number of dishes set up to make SETI observations at centimeter wavelengths. It is also used for radio astronomy. These dishes can observe our galaxy and other galaxies as well as gamma rays and radio sources.

9th & 10th Articles
The article "SETI" is about the history of SETI. According to the article, the origin of the search extraterrestrial intelligence was Cornell University in 1959 when Giuseppi Cocconi and Philip Morrison suggested using microwaves to communicate with aliens. It also discusses Project Ozma which was the first program to attempt to communicate with extraterrestrials. Other more recents projects Pioneer 10 and 11 which has engraved messages and Voyager 1 and 2 which both contain recorded audio. All four of these have left our solar system forever.
"Aliens Love Turkey?" discusses the large number of UFO sightings in Turkey as well as claimed contact with aliens. The author notes that Turkey citizens are typically very casual about sharing their UFO stories because it is so common to have UFO sightings in Turkey. The author provides no reasoning as to why this is.

7th & 8th SETI articles
The article "The Chance of Finding Aliens" by Govert Schilling and Alan M. MacRobert discusses the history of how the search for extraterrestrial intelligence became a point of interest. According to this article, the beginning of the search for life on other planets started with Giuseppe Cocconi and Philip Morrison in September 1959. They suggested that radio telescopes should be used to communicate with other intelligence. Another focal point of this article is the Drake equation. The Drake equation is important because it makes SETI tangible. The difficult part of it is to estimate the numbers to insert into the equation. Each number can vary from person to person and each greatly changes the final result.
"Life on Ceres: Could the Dwarf Planet be the Root of Panspermia" written by Ian O'Neill is about Ceres and the likelihood of it supporting life. Ceres is a dwarf planet that is located on the astroid belt that orbits around the sun. There is a large possibility that it may contain water. This is not the only reason scientists are enthusiastic about Ceres. It also has low mass just like Earth. All these qualities make it the best candidate for life in the solar system outside of Earth. These question will be answered once the Dawn spacecraft reaches Ceres in approximately five years.

5th & 6th SETI articles
http://www.popularmechanics.com/science/air_space/4332916.html?series=88
The article "10 Most Brilliant Innovators of 2009: Kepler Space Telescope" by Logan Ward discusses the recognition the Kepler Space Telescope received. This relates to SETI because the purpose of the Kepler Mission is to find Earth-like planets outside galaxy in hopes of finding other intelligent life. I also chose this article because we have a paper due about the Kepler Mission.

"The View from a Distant Star: Challenges of Interstellar Message-Making" by Douglas A. Vakoch is an article that includes multiple ways to communicate with extraterrestrial intelligence. This includes messages that could be seen from Earth, encoded pictures, and other options. Plenty of these have been attempted but none have been successful.
