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 GJ 1061?
g Abodes -New data from NASA's Mars Reconnaissance Orbiter and Mars Global Surveyor backs a theory that the Red Planet's huge northern hemisphere Borealis basin was created by an impact 3.9 billion years ago by a body some 1,200 miles in diameter, or larger than Pluto. See article.
g Life -Life on Earth might have emerged about 750 million years earlier than previously thought, new research suggests. See article.
g Message - The spectral approach is a universal tool of both astronomical observations and SETI. Furthermore, it has a clear physical meaning – a spectrometer finds the energy distribution of photons, in human sensing it is color and pitch. Under the hypothesis on identity of physical laws in our part of universe, it may be proposed that spectrometry also are using by those aliens, who know radio and lead theirs own SETI, too. See article.
g Cosmicus -Arthur C. Clarke died earlier this year aged 90. Known as “the colossus of science fiction”, Arthur became famous for his vision about futuristic communication satellites, the moon landings he foresaw, and much else. See article.
g Aftermath - If we find other civilizations, what will we say to them? Crafting a message that represents Earth and humanity and can be understood by another life form is no minor endeavor. SETI Institute psychologist Douglas Vakoch has been charged with this formidable task, and has enlisted the help of mathematicians, artists, astronomers and anthropologists. Hear the messages he helped compose and learn about the thinking behind them.
