When gas giants form and proposed European manned spaceship

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 - What is the habitable zone for the nearby star Gliese 687?
g Abodes - New research indicates that gas giants, like Jupiter and Saturn, form quickly after their stars do. In fact, they probably form within the first 10 million years of a star's life, or else they never form at all. See article.
g Life - A new study has found that, contrary to a long-held belief, marine species diversified early in history rather than becoming more diverse with time. See article.
g Message - Perhaps nothing says SETI Today more than the Allen Telescope Array, which is being built in collaboration with the Radio Astronomy Lab of the University of California, Berkeley. While the array is often described as a "dual use instrument," it would be more correct to say that it is a multi-tasking instrument. The simple implication that the array will conduct "SETI" and "other astronomy" is misleading. See article. Note: this article is from 2003.
g Cosmicus -A model of a proposed European manned spaceship has gone on show at the Berlin Air Show. See article.
g Aftermath - While no one can guarantee SETI’s success (the discovery of an alien civilization), that may not matter. At its deeper levels, SETI stimulates and influences our thoughts and transforms our society. See article.

Honoring the Past, Inspiring the Future
