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 - Special cameras on the IBEX spacecraft have snapped their first pictures of the complex interactions between space weather and Earth's magnetic field. The new data could help astrobiologists understand the links between the space environment and Earth's habitability. See article.
g Life - Life on Earth came from other planets, and has a genetic ancestry leading backwards in time over 10 billion years - so proclaims a revolutionary, paradigm busting text, “The Biological Big Bang”, edited by famed astrobiologist and astrophysicist Chandra Wickramasinghe. Chandra, along with his colleague astrophysicist Fred Hoyle, are often cited as the "fathers" of the field known today as "astrobiology." See article.
g Message - I’ve finally found online the classic paper published in Nature that initiated in 1959 the age of Electromagnetic SETI: “Searching for Interstellar Communications,” by Giuseppe Cocconi and Philip Morrison. See article.
g Cosmicus - Once regarded as the stuff of science fiction, antimatter - the mirror image of the ordinary matter in our observable universe - is now the focus of laboratory studies around the world. See article.

sorry.. but i didn't understand anything
What specifically did you not understand?
Ref your link: One would be making a hasty generalization to conclude that since the first radio astronomy search for ETI began 50 years ago and since we haven't heard from aliens that they must not exist. The search has only been periodical during the past half-century and has only examined an extremely small fraction of the galaxy (and there are a 100 billion more galaxies out there). ETI could exist within the region we've examined but simply is not technologically advanced enough to send or receive radio messages (humans have only been so for a little more than a century). Or they may be far more advanced and don't using "primitive" radio communication any more. Or we may have received a message - the Wow! Message is one possibility - and simply haven't gotten around to analyzing that ream of data yet. For more, read: http://www.guardian.co.uk/culture/2010/feb/07/extraterrestrial-life-robin-mckie
