Are we alone in this Universe? Could there be other intelligent life, besides us, out there? These questions haunt our imagination. Given the fact that our Universe contains two trillion galaxies, each with millions of stars and thousands of planets, it seems unlikely Earth is unique. Still, we have not found anything to suggest that extraterrestrial life exists.
In 1974, scientists used a 1,000-foot-wide telescope to send a carefully crafted radio broadcast into outer space, a message of zeros and ones meant to alert aliens to our existence. It was humanity’s first interstellar message intended to be picked up by aliens.
We haven’t heard back from ETs yet. Perhaps, there are aliens, but they choose to remain isolated or they could lack the technology to send or receive messages. Or perhaps, we are not listening properly.
