A Clear Signal From Outer Space
For half a century we have been searching the sky for extraterrestrial intelligence, using radio telescopes. This is on the assumption (debatable) that advanced ETs would still be communicating in the radio band. But what if they are trying to communicate with us in some other way? And what if their message to us isn’t one of cosmic brotherhood?
This gas “cloud” near the Eta Carina nebula seems to answer both questions. An extraterrestrial civilization does exist. It is sending us a very clear message using, not radio, but hand gestures. And the message isn’t what we were hoping for.
