On December 4, 2013, the U.S. House of Representatives Committee on Science, Space and Exploration held a hearing about the search for extraterrestrial life. It was given the title: "Astrobiology: The Search for Biosignatures in our Solar System and Beyond."
Below is the official hearing charter about the event.
Astrobiology: The Search for Biosignatures in our Solar System and Beyond Hearing Charter, December 4, 2013 [4 Pages, 400kb] - The purpose of this hearing is to examine astrobiology research and the search for biosignatures in our Solar System and beyond. The hearing will include a general assessment of the multi- and interdisciplinary nature of astrobiology research, including the role astrobiology plays in formulating NASA space missions.
The following documents are from the research collected on extraterrestrial life, civilizations, communication and exploration.
Extraterrestrial Life In The Universe [10 Pages]
The Search for a Rationale for Interstellar Communications [8 Pages, 600kb] - The paper explores the motives that have been given, or that might lie behind the expressed desire to communicate with other intelligent life forms living elsewhere in our Galaxy.
The Search for Signals of Extraterrestrial Life [10 Pages, 600KB] - The search for signals of extraterrestial life is connected with the general problem of existence and distribution of intelligent life in the universe, which for a long time was a province of science fiction or at the most a province of speculative conclusions. However recently it became an object of scientific research. More than that, a portion of the problem which relates to the form of life of the planets of the solar system has already been partially solved. On the basis of astronomical, radioastronomical, and direct experimental research, it can be concluded that not only do civilizations not exist on the nearest planets of the solar system, but even the existence of simple forms of life there is questionable.
