Interstellar messaging and questions about how dinos went extinct

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Life - Scientists have long believed that the Chicxulub crater in the northern Yucutan was evidence of a massive, extra-terrestrial impact that signaled the end of the dinosaurs. A new study indicates that this may not be the case. In fact, the dinosaurs may not have gone extinct until 300,000 years after the impact. See article.
g Message - Here’s a neat Web site: “Interstellar Messaging”. You’ll find discussion, history and real-world examples of mankind's methods and ongoing attempts to communicate with extraterrestrials.
g Aftermath - Humans live and die by approximations. We are seldom as perfect or as accurate as we would like to be. And as we contemplate what we might say to an advanced extraterrestrial civilization, maybe that's a point we should emphasize. See article. Note: This article is from 2003.
