NASA’s efforts to plan a future mission to Europa

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Intelligence - A new study from Lund University in Sweden shows that the average life expectancy of men and women with schizophrenia is 15 years and 12 years shorter respectively than for those who do not suffer from the disease. The study has been carried out in collaboration with Stanford University in the United States. 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 Cosmicus - Here’s a series that follows an oceanographic expedition to the Mid-Cayman Rise and NASA’s efforts to plan a future mission to Jupiter’s moon, Europa. In part five, scientists use high-tech submersibles to explore the seafloor and bring intriguing samples up to the surface. See article.
