Do other planets harbor life and new response to the Fermi Paradox

Welcome! “Alien Life” tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here’s today’s news:
g Stars - Astronomers at the Carnegie Institution have found the first indications of highly complex organic molecules in the disk of red dust surrounding a distant star. The eight-million-year-old star, known as HR 4796A, is inferred to be in the late stages of planet formation, suggesting that the basic building blocks of life may be common in planetary systems. See article.
g Abodes - Most people have looked up at a starry sky and wondered whether there is life beyond our own blue planet. Is our world a unique oasis of life or are there other planets that harbor life? See article.
g Life - Whether a similar bounty of life exists elsewhere in the universe is one of the oldest and most tantalizing questions of science. Considering the wide breadth of the universe and the countless stars it contains, the odds would seem in favor of the answer being "yes." See article. Note: This article is from 2007.
g Message - The famous question posed by the physicist Enrico Fermi in 1950 remains unanswered. "Where is everybody?" he asked. If the galaxy is teeming with sophisticated aliens, we should have heard from them by now. A new response to the Fermi Paradox comes in a recent issue of the journal New Astronomy. The aliens, like the truth, may be out there - but perhaps are so far out that there's no hope of receiving even a text message. See article. Note: this article is from 2006.
