How Earth became habitable for life and our gold record message to the stars

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 - Scientists have proposed an answer to a long-standing question concerning the formation of the Earth's interior and the gases that lie trapped deep beneath our planet's surface. The research will help astrobiologists understand how our planet formed and ultimately became habitable for life. See article.
g Life - We may not be unique "alone" living beings in the cosmos. Perhaps, at this time, on a sidereal body barely heated by a small star, or on a world illuminated by a binary or a multiple star system, someone is asking itself (him, her or both) the same thing. See article.
g Message - When the Voyager 1 and 2 spacecraft were launched in 1977, they each included a gold-plated phonograph record (a "golden record") of natural sounds, greetings in human voices, and a variety of music. The record cover has symbolic instructions that show how to use and understand the record, though scientists still debate whether other civilizations will be able to decipher them. For info on Voyager’s golden record, see article. For an explanation of the record cover diagram, click here. For an interactive module that contains greetings, sounds, and pictures included on the record (requires Flash plug-in), click here.
g Cosmicus - Looking around the stellar neighborhood, what interesting things could demand our attention, technologically? See article.
