Are we alone?

One of my favourite podcasts in English has talked about constructed languages in general, and has obviously mentioned Esperanto. It is “Are we alone?”, the podcast of the SETI Institute, devoted to the search of extraterrestrial intelligence, but also to the spread of scientific knowledge.

You can read about the content here, and you can download it here.

Obviously, the title doesn't concern Esperantists: we are never alone!
