Could extraterrestrial life exist in the Alpha Centauri solar system?

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 - Could extraterrestrial life exist on a planet in the Alpha Centauri solar system? See article.
g Abodes - Curiosity has tracked a trail of minerals on Mars that indicates water was once present in Gale Crater on Mars. Curiosity's ChemCam instrument detected veins composed mainly of hydrated calcium sulfate, such as gypsum. On Earth, forming such features requires liquid water. See article.
g Message - Seth Shostak is an astronomer, specifically a radio astronomer. That is, he looks at radio signals coming from space from various cosmic objects.

He looks for aliens.He tell you all about it, in this TEDxSanJose talk he gave in April 2012. See article.
