How life survived asteroid impacts and looking for messages left for us during the past several hundred million years

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 - Natural catastrophes such as asteroid impacts, massive volcanic eruptions or large-scale wildfires would have periodically plunged our planet into abnormal darkness. How did life survive without the sun's life-giving rays during such episodes? With a little help from organisms that can switch to another source of energy while they wait for sunlight to pierce the darkness once more. See article.
g Message - The world-renowned physicist Lee Smolin author of “Life of the Cosmos” says that what we should look for to confirm the existence of intelligent life in the Milky Way is a message left for us some time in the last several hundred million years. See article.
g Learning - Stories about the fictional planet Nibiru and predictions of doomsday in December 2012 have blossomed on the Internet. As of June 2009, more than 175 books listed on Amazon.com dealing with the 2012 doomsday. As this hoax spreads, many more disaster scenarios are being suggested. “Ask an Astrobiologist” has received nearly a thousand questions about Nibiru and 2012, with more than 200 answers posted. Many new questions are similar to those already answered. Here is a list of the most popular “Twenty Questions” organized in a logical succession and answered in some detail.
g Aftermath - You may have to really scour used book stores for this one: 1976’s “ETI: The First Encounter” considers the consequences to man's view of himself and his world of the first proven contact — when it comes — with beings from another planet. Edited by James L. Christian, this book led the way in reflecting on the next stage in man's gradual self-discovery. See the table of contents and ISBN.
