Which aliens we can hear and the Galaxy Zoo

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 - Do you have an Internet connection, some free time and a penchant for staring off into space? Then Galaxy Zoo needs you – to classify galaxies. See article.
g Abodes - Miles Below Antarctica's icy surface, scientists are finding abundant life in liquid lakes and rivers. See article.
g Message - When someone tells you the aliens couldn't possibly hear us, you can just smile politely. The truth is, they could. And what about us hearing them? We've only had radio for a century. Some extraterrestrials have surely had it for a hundred or thousand times longer. If our signals are detectable, theirs might be far more so. See article. Note: This article is from 2008.
g Aftermath - If we find other civilizations, what will we say to them? Crafting a message that represents Earth and humanity and can be understood by another life form is no minor endeavor. SETI Institute psychologist Douglas Vakoch has been charged with this formidable task, and has enlisted the help of mathematicians, artists, astronomers and anthropologists. Hear the messages he helped compose and learn about the thinking behind them.
