Carbon emission line from most distant galaxy known so far
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 - Astronomers have detected a carbon emission line from the most distant galaxy known so far. The faint galaxy shows that carbon existed less than a billion years after the Big Bang. Determining the composition of the early Universe can help astrobiologists understand when and where habitable planets could have formed. See article.
g Abodes - ESA's Venus Express has discovered an ozone layer on Venus. Comparing Venus' ozone layer to those on Earth and Mars will help astrobiologists refine the search for life on other planets. Comparing Venus to Earth can also help scientists better understand the principles of climate change on our own planet. See article.
g Message - The Earth's radio emission is now comparable to or stronger than the Sun's. So for aliens looking in the radio frequency, we should be the brightest spot in the solar system. 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
