First directly observed extrasolar planet is orbiting a sun-like star confirmed and responses to Fermi Paradox

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 - Astronomers have confirmed that the first directly observed extrasolar planet is orbiting a sun-like star. The planet is adding to our knowledge of how planetary systems form and can help astrobiologists better understand where to search for habitable worlds around distant stars. See article.
g Message - Book alert: In response to Enrico Fermi's famous 1950 question concerning the existence of advanced civilizations elsewhere, physicist Stephen Webb in “If the Universe Is Teeming with Aliens... Where Is Everybody? Fifty Solutions to Fermi's Paradox and the Problem of Extraterrestrial Life” critically examines 50 resolutions to explain the total absence of empirical evidence for probes, starships, and communications from extraterrestrials. He focuses on our Milky Way Galaxy, which to date has yielded no objects or signals that indicate the existence of alien beings with intelligence and technology. His comprehensive analysis covers topics ranging from the Drake equation and Dyson spheres to the panspermia hypothesis and anthropic arguments. Of special interest are the discussions on the DNA molecule, the origin of life on Earth, and the threats to organic evolution on this planet (including mass extinctions). Webb himself concludes that the "great silence" in nature probably results from humankind's being the only civilization now in this galaxy, if not in the entire universe. This richly informative and very engaging book is recommended for most academic and public library science collections. See article.
g Imagining - Like stories about efforts to communicate with alien? Then be sure to read Fred Hoyle’s “A for Andromeda” (1962). See article.
