Moon mysteries and ‘Where’s ET?’

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 Abodes - The moon - linked in myth with goddesses of witchcraft and the hunt, with gods of magic and wisdom - is nearly as old as Earth itself, with enigmas of its own. As close as the moon is to Earth, we are still far from solving all its mysteries, from how the moon was born to whether life on Earth has its past and future there. See article.
g Cosmicus - Quote of the Day: "All civilizations become either spacefaring or extinct.” – Carl Sagan
g Learning - The fact that you’re confronting this column on a website devoted to space science and astronomy makes you roughly as rare as technetium. Despite the fact that astronomy is one of the two most popular science subjects in American schools (the other is biology), it’s really not that popular. See article.
g Imagining - Book alert: "Extraterrestrials, Where Are They?" by Ben Zuckerman and Michael H. Hart (ed.) offers a critical analysis by leading experts in a range of sciences, of the plausibility that other intelligent life forms do exists. Exploration of the solar system, and observations with telescopes that probe deep space, have come up empty-handed in searches for evidence of extraterrestrial life. Many experts in the fields of astronomy, biology, chemistry and physics now argue that the evidence points to the conclusion that technological civilizations are rare. After 10 billion years and among hundreds of billions of stars, we may well possess the most advanced brains in the Milky Way. This second edition elucidates many new aspects of research on extraterrestrial intelligence life, specifically biological considerations of the question. Read more reviews.
