Arecibo Observatory’s search of artificial radio signals and how comets may have aided life’s start

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - For the first time, astronomers have observed a tumbling comet nucleus with a changing rotational rate. The study combined with results from NASA's EPOXI mission are providing new insight about these objects that may have played a role in life's origin on Earth, and could also play a role in future exploration. See article.
g Life - A new fossil recovered in China indicates that bird and crocodile family trees split earlier than previously thought. See article.
g Message - Here’s a prerecorded Web cast at Aricebo Radio Observatory in March 2003 when scientists listened to the most promising transmissions from UC Berkeley’s SETI@home search. Join the Exploratorium’s Ron Hipschman and special guest Dan Werthimer, chief scientist and principal investigator for the SETI Institute’s efforts, as they also discuss Arecibo Observatory’s search of artificial radio signals coming from other stars here; scroll to “What about Intelligent Life?”
