Multiple universes and Mars’ hydrothermal springs

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 - The opening speaker at the 2008 Astrobiology Science Conference, Lord Martin Rees of the University of Cambridge, said that our universe may just be one of many. Multiple universes could be stacked sideways like sheets of paper, separated by only a thin margin of space. We would never know they were there unless we could be awakened to the existence of that other dimension. See article.
g Abodes - There's a growing buzz in the astrobiology community that ancient hydrothermal springs may have been spotted on Mars. See article.
g Message - No matter how quiet we try to be now it's too late to prevent alien invaders. So says Alexander Zaitsev of the Institute of Radio Engineering and Electronics in Moscow, Russia, who points the finger at astronomers. See article.
g Imagining - Speculation about aliens has typically been left to science fiction authors, science fiction readers and Hollywood writers and directors. But what if we apply what we have learned about life on Earth to speculate about what alien life forms might be like? Here’s a primer.
