Some of Earth’s minerals came from outer space and a memorial to Big Ear

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 - Researchers have presented a new view of the region of the sun’s influence, or heliosphere, and the forces that shape it. See article.
g Abodes - According to a new study by geologists, the wealth of some minerals that lie in the rock beneath the Earth's surface may be extraterrestrial in origin. See article.
g Life - Conservation biologists are setting their minimum population size targets too low to prevent extinction. See article.
g Intelligence - Centenarians with the bodies of 50-year-olds will one day be a realistic possibility, say scientists. See article.
g Message - In late 1997, after almost 40 years of operation, the Ohio State University Radio Observatory and its "Big Ear" radio telescope — which picked up the famous “Wow!” signal — ceased operation. The land on which the observatory was sitting (owned by the Ohio Wesleyan University, Delaware, Ohio) was sold in 1983 to land developers who later claimed their rights to develop the property. The telescope was destroyed in early 1998. Here’s a Web page memorial to Big Ear.
g Cosmicus - Teleportation, time travel, antimatter and wireless electricity. It all sounds far-fetched, more fiction than fact, but it's all true. See article.
g Learning - A new exhibition marking the 400th anniversary of Galileo's work is set to open in the Vatican. See article.
g Aftermath - Few terms in the space vocabulary are as polarizing as this three-letter acronym: UFO. For some, it represents not just Unidentified Flying Objects, but a virtual universe of extraterrestrial visitations, alien abductions, and—of course—a vast web of government and multinational conspiracies to deny their presence. To others, it’s a symbol of hoaxes and fantasies or, at best, wishful thinking. For those in the latter camp, there might be some trepidation to pick up a book titled “Beyond UFOs”. Rest assured, though: despite the presence of that three-letter acronym, this book is actually a solid, factually-based look at the science of astrobiology and the prospects for lif e— intelligent or otherwise — elsewhere in the universe.
