  1. What is Astrobiology? “Astrobiology is the study of life in the universe. It investigates the origin, evolution, distribution, & future of life on Earth, & the search for life beyond Earth. Astrobiology addresses three fundamental questions: 1) How does life begin & evolve? 2) Is there life beyond Earth & how can we detect it? 3) What is the future of life on Earth & in the universe?” (http://astrobiology.arc.nasa.gov/)

  11. Arecibo Radio Observatory (Puerto Rico) 305-meter diam. Phoenix Project 1995-present survey of 1000 nearby stars at freq. of 1000-3000 MHz Project SERENDIP 1979-present “piggy-back” survey using various radio telescopes. Arecibo observations (1992-present) scan each sky pointing every 1.7 seconds over 168 million channels centered on 1420 MHz. This enormous data load is farmed out to SETI@home

  12. Allen Telescope Array (Hat Creek, California) 350 6-meter dishes (2008) This privately-funded (mostly by Microsoft co-founder Paul Allen) telescope will be primarily used by the SETI Institute for SETI surveys. It will be able to scan a wide field of view (2.5 degrees) over a wide frequency range (0.5-11.2 GHz) at each pointing. Over 50 dishes are already in place and taking data for several projects.
