Earth-like planets around low-metallicity stars and ancient planetary system discovered

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 - New research predicts the criteria needed for Earth-like planets to form around a star that have one-tenth the metallicity of our Sun. If researchers find small, rocky planets orbiting stars with lower metallicity, it may challenge the presently accepted "core accretion" model of planetary formation. See article.
g Abodes - Astronomers have discovered an ancient planetary system that could be a survivor from 13 billion years ago. See article.
g Cosmicus - The Canadian Astrobiology Network, centered at Western University, is a network of institutions and researchers across Canada that is actively engaged in this type of astrobiological research and effective immediately, CAN has been elevated to affiliate status within the NASA Astrobiology Network.
