Active SETI and commercial travel to outer space routine by 2012

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - Prevailing theoretical models attempting to explain the formation of the solar system have assumed it to be average in every way. Now a new study by Northwestern University astronomers, using recent data from the 300 exoplanets discovered orbiting other stars, turns that view on its head. See article.
g Abodes - The search for Earth-like life on other worlds should focus on solar systems with Jupiter-like planets, a University of Arizona scientist reports. See article. Note: This article is from 2001.
g Message - Recent discussions within the SETI community have thoroughly explored the issue of whether people with access to radio telescopes should send powerful signals to alien civilizations without some process of prior international consultation. In particular, those exchanges have focused on the question of "Active SETI." See editorial.
g Cosmicus - Routine commercial travel to outer space may be the norm as soon as 2012, as the next generation of spacecraft — designed by private sector firms like Virgin Galactic, Orbital Sciences Corp., Space Exploration Technologies Corp. and others — transport adventure-seeking civilians into low-Earth orbit. See article.
g Aftermath - The search for extraterrestrial life grips the human imagination because it tells us about ourselves. See article. Note: This article is from 2003.
