Austrinus It is the astronomy site of Farid Char.
This space was inaugurated on 11/25/2000 and its name means “austral” or “from the south” in Latin.

This name serves to better identify the origin of its contents, created from the Southern Hemisphere: 23°39' S and 70°25' W (Antofagasta, Chile).

In astronomy, the name is present in the constellation Pisces Austrinus.

Exobiology

Posted byFarid

Exobiology is defined as the study that seeks to find traces of life on other planets other than Earth; Research in this area is usually discouraging, as no vestiges of other forms of life or planets with the necessary conditions to support it are found; However, statistically it is thought that there are a large number of planets orbiting other stars that could harbor life, whether in a primitive or intelligent state. Studies so far are limited to the detection of exoplanets, which almost exclusively consist of gas giants without a solid surface; but there is also the famous SETI project, dedicated exclusively to capturing possible extraterrestrial radio signals.

The Drake Equation

Frank Drake, then director of the Institute for the Search for Extraterrestrial Intelligence (SETI), formulated the so-called "Drake equation«; It says: N= R* x fp x ne x fl x fi x fc x L. Where:

  • La N : Number of intelligent ET civilizations that could exist in our Milky Way
  • R* : Rate of formation of stars suitable for life
    fp : fraction of stars with planets around them
  • ne : Number of planets in each system with an environment suitable for hosting life forms.
  • fl : Fraction of those planets on which life has developed.
  • fi : Fraction of such planets on which intelligent life has developed.
  • fc : Fraction of such planets on which intelligent life has developed technology and attempts to communicate with others.
  • l : Estimated lifespan that these intelligent civilizations can exist, before their disappearance.

It consists of determining how many stars there are in each galaxy, how many of those stars have planets, how many of those planets have life, how many of those beings are intelligent, how many wish to communicate with beings from other planets and what is the estimated lifespan of said beings. without falling into their own self-destruction. The final figure, which in principle could be reduced to almost nothing, surprisingly reveals that only in our galaxy could they exist. 10,000 civilizations.

Scientific studies in exobiology have also aimed to describe other areas of our Solar System, apart from Earth, where life could possibly arise. But popular culture is not exempt from all this, which has added a mythical element to the matter: the alleged UFOs and encounters with ET beings.
