Nearby galaxy’s star making almost over and creating an Earth-based comet

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 - Galaxies throughout the universe are ablaze with star birth. But for a nearby, small spiral galaxy, the star-making party is almost over. See article.
g Life - Trails found in rocks dating back 565 million years are thought to be the earliest evidence of animal locomotion ever found. See article.
g Message - Would anyone deliberately beam high-powered signals into space? Can we assume that extraterrestrial societies would broadcast in ways that would mark their location as plainly as a flag on a golf green? See article. Note: This article is from 2003.
g Cosmicus - New Mexico's Spaceport America is no longer the stuff of fancy graphics. See article.
g Learning - Dr. Dennis Schatz created the first "Earth-based" comet many years ago. His very popular demonstration is conducted in classrooms and science museums around the world. You can build a comet following Schatz's very own recipe, "Making a Comet in the Classroom".
g Aftermath - What are the societal implications of astrobiology? A NASA workshop in 1999 set out to determine what they might be. Here’s their report.
