Carbon-rich stars and ‘The Earth After Us’

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Stars - Astronomers have found evidence that carbon-rich stars may form at the center of the Milky Way. The research is helping astrobiologists understand how elements necessary for life are formed and distributed through the universe. See article.
g Intelligence - Book alert: In “The Earth After Us”, geologist Jan Zalasiewicz invites the reader to take a step in the scientific imagination far greater than that involved in looking at the Earth from the Moon, as the cover depicts. For the challenge taken up by the book is to look back at human civilization from a vantage point in time long after the human species itself has disappeared, through observations made by alien beings visiting the planet for the first time. See review.
g Cosmicus - With the launch of the "Kepler" spacecraft arises new hopes and dreams for what could be an earth-shattering answer to a question as old as time: Are there other earths just like ours? See article.
