‘Aliens’ from Earth’s deep set and rethinking plans for managing first contact

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - ESA's Mars Express orbiter has captured the first image to show Mars' moons Phobos and Deimos together in a single frame. The image will help scientists refine orbit models of the two moons. See article.
g Life - Astrobiologists have not yet found alien life on other planets. But the fossil record has evidence of aliens of another sort: the Ediacarans that lived on Earth millions of years ago. See article.
g Message - In 1974, astronomers sent the "Arecibo message," a binary-coded signal that decodes to a graphic illustrating some basic characteristics of Earth. The message was intended more to demonstrate the power of the telescope than to contact distant civilizations. Cornell's 25th anniversary announcement includes a decoded explanation and more information about what the scientists were thinking. See article. Note: This article is from 1999.
g Aftermath - Astrobiology is more than an esteemed partner conducting routine grunt work to increase our confidence that SETI will lead to a confirmed detection. Advances in astrobiology force us to rethink our search strategies and our plans for managing contact and its aftermath. See article.
