Icy dust could be precursor to molecule for life's building blocks
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - What is the potential habitability of the nearby star system BD-05 3853 AB? See article.
g Abodes - If Mars ever had oceans, lakes or rivers, then it may also have had life as we know it. Indications of liquid water on the Red Planet have tantalized scientists for well over a century. See article.
g Life - New research is shedding light on the chemistry that occurs in the dark space between stars. Astrochemists have demonstrated a key role that icy dust could play in the formation of a precursor molecule for life's building blocks. 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
