Dark matter’s origin, mass hystera over metoerite and astrobiology in science fiction

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 - Some of the universe's first stars might still be lighting up their corners of the cosmos, new computer models suggest. And finding these stellar oldies could reveal something about the nature of dark matter. See article.
g Abodes - What are the lines of evidence that indicate whether an extrasolar planet is able to support life? See article.
g Intelligence - On what started as a normal Saturday night one week ago, residents of a small, remote Peruvian town saw a bright light streak across the sky, heard a resounding bang and suddenly found themselves at the center of a media frenzy. See article.
g Cosmicus - Quote of the Day: “Though my soul may set in darkness, it will rise in perfect light; I have loved the stars too fondly to be fearful of the night.” - Sarah Williams
g Learning - How are key concepts of astrobiology treated in science fiction? See article. Note: This article is from 2001 and intended to be used as part of a classroom lesson.
g Imagining - Like first contact stories? Then be sure to read C.M. Kornbluth’s short story "The Silly Season," originally published in F&SF (Fall 1950).
g Aftermath - How would proof of extraterrestrial intelligence affect humanity’s “world” view? Astronomer Steve Dick discusses the matter in this transcribed Smithsonian Institute lecture, from 1999.
