\textit{Oh, an empty article!}   You can get A revolution has occurred in the last two decades in the world of astrophysics.   It all  started in the early '90s with the discovery of 'new worlds' around other stars. The world 'Extrasolar planet' (or Exoplanet) started being widely used to identify planets\footnote{A planet is a celestial body massive enough to be bounded  by \textbf{double clicking} this text block and begin editing.

The most remarkable discoveries came in the last 2-4 years thanks to the KEPLER space telescope that, looking at the tiny dimming induced by the passage of a planet in front of its host star, was able to answer two fundamental questions:   \begin{enumerate}   \item How common are planets?   \item How common are planets similar to Earth?   \end{enumerate}   It is clear that the answer to these questions have a profound impact not only for astrophysics, but more generally to
