The not-so-lonely planet?
In April astronomers announced the discovery of an earth-like planet.
It is 39 light years away with an atmosphere. Could this be an inhabited world? We are given the impression that aliens are everywhere. There are movies like ET, Independence Day or Close Encounters. There are books like War of the Worlds or The Hitchhiker’s Guide to the Galaxy. Classics among video games are Space Invaders and Defender.
