Worlds beyond our own
  We give a popular account of the present state of the research in the field of extra-solar planetary systems, popularly termed as exoplanets, with a brief overview of the techniques employed. We also discuss the question of habitability and the possibility of finding intelligent life elsewhere in the Milky Way. We conclude with a brief exposition on the less explored territory of exomoons.
