Connections between a planet's physical properties and its habitability, and no cryptologists standing by at SETI

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 - An exhaustive study of nearly half a million deformed galaxies observed by the Hubble Space Telescope has revealed definitive proof of the acceleration of our universe's expansion. See article.
g Abodes - A new model of the Earth is helping scientists understand how our planet's surface moves and deforms. The model shows Earth's tectonic plates as a dynamic, 3D puzzle, and could help astrobiologists understand the intricate connections between our planet's physical properties and its habitability for life. See article.
g Message - Modern SETI searches are looking for technically sophisticated aliens around other star systems. Do the research teams that run these experiments also have cryptologists standing by? See article. Note: This article is from 2000.
g Learning - The constellations we’re generally familiar with generally comes from the ancient Greeks and Romans. Here’s a neat Web site that teaches kids about alternate constellations – those in the Lakota Sioux tradition.
