Titan’s weather and amino acids in comets

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 - What is the habitable zone for the nearby star GJ 213?
g Abodes - New evidence suggests that the parched, dry deserts of Saturn's moon, Titan, can support large-scale storms. Significant cloud formation has been witnessed over Titan's tropical zone near the moon's equator. See article.
g Life - NASA says it has identified an amino acid, one of the key building blocks of Earth-style life, in material recovered from a comet far out in space. They say this supports the idea that life may be commonly found throughout the universe, and that they have eliminated the chance that the cometary sample has been contaminated by Earthly life. See article.
g Message - Whenever the director of SETI research presents a public lecture, she can almost guarantee that “What If everybody is listening and nobody is transmitting?” will be one of the questions the audience asks. See article.
g Aftermath - The discovery of life elsewhere in the Solar System would 'profoundly change our understanding of where we came from and our place in the cosmos', astrobiologist Lewis Dartnell says. See article.
