This blog is dedicated to one event that very well may compel us to becoming a space-faring race: contact with an extraterrestrial civilization. It is a serious site; you won’t find a discussion of UFOs and the Fifth Dimension’s denizens here. Instead, it updates readers daily of the latest scientific advances in a number of fields related to the multidisciplinary study of astrobiology. Its sections are loosely arranged around the now famous Drake equation, developed by astronomer Frank Drake, who conducted the first modern search for extraterrestrial life in 1960.The equation seeks to determine the number of technological civilizations that might exist among the stars:
R * FP * NE * FL * FI * FC * LN = N
In the equation, R is the mean rate of star formation averaged over the lifetime of the galaxy; FP the fraction of stars with planetary systems; NE the mean number of planets per system with environments suitable for the origin of life; FL the fraction of such planets on which life does develop; FI the fraction of such planets on which intelligent life rises during the lifetime of the local sun; FC the fraction of planets on which advanced technical civilizations rises; L the lifetime of this technical civilization; and N the number of advanced technical civilizations emitting detectable radio signals.This blog’s sections and the general topics addressed in each one include:
g Stars - Cosmology and astronomy, which affect our understanding of the mean rate of star formation averaged over the lifetime of the galaxy and the fraction of stars with planetary systems, or R and FP in the equation
g Abodes - Geology and Earth climate, which helps us grasp the mean number of planets per system with environments suitable for the origin of life, or NE in the equation
g Life - Biology, especially the evolution of life, as well as chemistry and other sciences that advance our understanding of the fraction of such planets on which life does develop, or FL in the equation
g Intelligence - How homo sapiens and, more generally, intelligence evolves, to help us determine the fraction of such planets on which intelligent life rises during the lifetime of the local sun, or FI in the equation
g Message – A discussion of our attempts to communicate with our other intelligences, to increase our knowledge of the fraction of planets on which advanced technical civilizations rises, or FC in the equation
g Cosmicus - Humanity's climb to the status of a space-faring civilization, a necessary step to increase the lifetime of this technical civilization, or L in the equation; the term “cosmicus” comes from the father of Russian astronautics, Konstantin Tsiolkovsky, who envisioned humanity becoming “homo cosmicus” or a space-faring civilization — we will become “homo cosmicus” when the first human is born, lives, grows old and dies in space, returning to Earth only as a visitor

g Learning - Science education, as humanity's future and astrobiology's success depends upon a science-literate youth and public; it also is a necessary step to increase the lifetime of this technical civilization, or L in the equation
g Imagining – This section consists of musings on the possibilities of science fiction aliens as science fiction offers a literary portal for us to examine elements of the Drake Equation; I’ll primarily focus on “Star Trek,” the most popular and serious of the science fiction genres
g Aftermath – Looking beyond the Drake Equation is perhaps the most important question that will face humanity in the century ahead: “What will happen after we make contact with aliens?”; this section offers the latest speculations
I hope each of you will return daily to stay current with astrobiology — and that it may inspire you to work toward the day when humanity becomes homo cosmicus.
