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 nearby Kapteyns Star?
g ABODES - It used to be that planets were familiar places such as Mars and Saturn that orbited our sun and were well known to all schoolchildren. Since astronomers identified the first planet outside our solar system 13 years ago, however, that idea has become downright quaint. Because now, according to the Extrasolar Planets Encyclopedia, there are 277 confirmed "extrasolar" planets, and quite a few more on the list of those suspected but not yet confirmed. See article.
g LIFE - NASA-funded researchers are refining a tool that could not only check for the faintest traces of life's molecular building blocks on Mars, but could also determine whether they have been produced by anything alive. See article.
g MESSAGE - In the search for life on other worlds, scientists can listen for radio transmissions from stellar neighborhoods where intelligent civilizations might lurk or they can try to actually spot planets like our own in habitable zones around nearby stars. Either approach is tricky and relies on choosing the right targets for scrutiny out of the many thousands of nearby stars in our galactic neighborhood. See article.
