Machines as universe’s predominant species and exoworld in habitable zone

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - Astronomers have detected close to 500 distant alien worlds so far — one of which is the right distance from its star to sustain liquid water and possibly even life — and new advances are yielding more planet discoveries faster than researchers can verify them. See article.
g Cosmicus - New data from NASA's LCROSS and LRO missions indicates that lunar soil within shadowy craters is rich in materials that could be useful for future human explorers. The findings also indicate that the Moon is chemically active and has a water cycle. See article.
g Learning - Carl Sagan, Cornell University faculty from 1971 to 1996, is considered one of greatest popularizers of science. See article.
g Imagining - As early as 2003, when he became NASA’s chief historian, Dr. Steven Dick was punching holes in fellow astronomers’ efforts to contact ET through radio technology. Writing for the International Journal of Astrobiology that year, he warned that SETI searches were failing to make allowances for any “cultural evolution” that could be shaping off-world societies, which “may have resulted in a postbiological universe in which machines are the predominant intelligence.” See article.
g Aftermath - Astronomer Royal, Sir Martin Rees describes how for the first time humans as a species may start to change in observable ways within single lifetimes and under some loose control of our own influence. If this future plays out, the future itself becomes more difficult to forecast. See article. This article is from 2005.
