Questions discussed at Origins and a new NASA-ESA alliance

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Life - A fossil of a primitive "walking seal" with four legs and webbed feet has been found in the Canadian Arctic and dated to be at least 20 million years old. See article.
g Intelligence - How did the universe begin? How did life begin? Is there intelligent life beyond Earth, or are we alone in the cosmos? These were some of the questions addressed at a remarkable symposium titled “Origins,” when distinguished scientists from a broad spectrum of disciplines gathered in Phoenix in early April. See article.
g Message - The structure of terrestrial music might provide clues to creating interstellar messages that could be understood by extraterrestrial intelligence. In the process, he suggests that music may provide a means of communicating "something of our consciousness that is essentially human, regardless of the civilization from which it emerges." See article. Note: This article is from 2002.
g Learning - NASA has selected two science investigations that will forge new alliances between NASA and the European Space Agency. The projects will also advance our knowledge of terrestrial planets in our solar system. Collaboration on the ExoMars mission in particular is set to help astrobiologists understand whether or not Mars was once habitable for life. See article.
