هل توجد حياة في الفضاء الخارجي؟

Welcome to BBC Xtra English.

Today John and Reda ask "Is there anyone out there?"

Is there life in outer space? This week messages have been transmitted by a radio telescope from Earth to a planet twenty light years away.

The planet was chosen because scientists think it is capable of supporting life; they want to see if there is intelligent alien life there.

If anyone gets the messages, it will be forty years before we receive a reply.

The messages have been collected from users of the social networking site, Bebo.

Young people have written about many things, including their fears and hopes for the future. It has been called a snapshot of a generation.

If you could send a message to outer space, what would it be? Write to us in English.
