Different forms of SETI through history and deepest known hydrothermal vent

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 - The Sun is equivalent to 80 billion hydrogen bombs exploding every second, but it is just a little star. See article. This article is from 2000.
g Abodes - An expedition partially funded by NASA has discovered the deepest known hydrothermal vent in the world. Studying the site, 5000 meters below the Caribbean Sea, can help astrobiologists understand the limits of life on Earth. See article.
g Life - Every day, millions of microorganisms travel with the wind from one place on Earth to another. Bacteria, funguses and viruses on dust particles can move thousands of kilometers. A team of researchers has now found that the phenomenon is escalating with climate change. See article.
g Intelligence - Is there obvious proof that we could be alone in the galaxy? Enrico Fermi thought so - and he was a pretty smart guy. Might he have been right? See article. This article is from 2001.
g Message - The search for extraterrestrial life has taken many forms through the years starting with pure imagination. See article.
g Cosmicus - NASA's Wide-field Infrared Survey Explorer, or WISE, completed its first survey of the entire sky. Among the more than one million images of everything from asteroids to distant galaxies, WISE has discovered over 90 near-Earth objects. See article.
g Aftermath - Look for an intriguing book to read: “Space, the Final Frontier?” by G. Genta e M. Rycroft. Published in 2003. The book primarily examines how we can become a spacefaring civilization, but it does include an interesting chapter about life in the universe, the Search for Extraterrestrial Intelligence, the Drake Equation, intelligent lifeforms, whether other lifeforms will be more like ET or Alien, and the possible humanoid characteristics of extraterrestrials. See commentary and table of contents.
