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 Abodes - Heres a paper that presents a general modelling scheme for assessing the suitability for life on any Earth-like extrasolar planet. The paper’s approach is based on an integrated Earth system analysis in order to calculate the habitable zone in main-sequence-star planetary systems. A new attempt to estimate the formation rate of Earth-like planets over cosmological time scales is applied to calculate the average number of habitable planets in the Milky Way as a function of time. See article.
g Life - Velociraptors, tyrannosaurs and other related carnivorous dinosaurs breathed like some of today’s diving birds and consequently were probably speedy predators, a new study finds. See article.
g Cosmicus - Giant-sized telescopes such as Hubble, Spitzer and Chandra offer unprecedented views of the cosmos, but astronomers are eager to put more powerful tools into orbit around the Earth. See article.
g Learning - We learn better when the material meshes with what we already know, according to a new study of rats that researchers say could help explain human learning. See article.
