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 - New analysis of complex chemical activity on Titan is raising questions about the potential for primitive, exotic life on the Saturnian moon. According to one theory, the chemical signatures fulfill two important conditions necessary for a hypothesized “methane-based life.” See article.
g Message - Here’s an intriguing piece: “There is No Fermi Paradox.” The "Fermi Paradox," an argument that extraterrestrial intelligence cannot exist because it has not yet been observed, is a logical fallacy. This "paradox" is a formally invalid inference, both because it requires modal operators lying outside the first-order propositional calculus and because it is unsupported by the observational record. See article.
g Cosmicus - Modern space telescopes and ground-based telescopes provide a wealth of data for astronomers. Like Galileo discovering Jupiter's moons, scientists today hunt the skies for new and mysterious objects. See article.

The Drake Equation
This formula estimates the number of intelligent civilizations in our galaxy.N=(R*)(Ns)(Fp)(Ne)(Fl)(Fi)(Fc)(L)
Where:- N = Number of civilizations we can communicate with
- R* = Average star formation rate
- Ns = Percentage of stars capable of supporting earth-like planets
- Fp = Percentage of those stars with planets
- Ne = Average umber of planets in those stars' habitable zones
- Fl = Percentage of those planets where life begins
- Fi = Percentage of planets with life where an intelligent species evolves
- Fc = Percentage of those intelligent species that develop communication technology
- L = Average lifetime, in years, of a civilization that develops such technology

- I'm the owner and chief editor at Inventing Reality Editing Service, which meets the editing and proofreading needs of writers both new and published. For more than two decades, I worked as an award-winning journalist, with half of those years spent as an editor.
