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 - Volcanic activity can cause short-term variations in climate. Now, new research shows that the reverse is also true. See article.
g Cosmicus - New calculations indicate that seeing infertile areas of the oceans would cause enough of an increase in photosynthesizing marine life to address carbon emissions. See article.
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.
