Recently, scientists at NASA discovered seven Earth-sized planets just about 40 light-years away from us, three of them are situated in a habitable zone. Findings like this one make one wonder if this means that we’re a step closer to contacting intelligent life elsewhere.
While today many scientists don’t see it as a priority, it has crossed the mind of few people that perhaps we should take the initiative and sending them a message. Fortunately for most of us, exactly 40 years ago, experts have already sent a compilation of sounds and images to the unknown cosmos.
As part of the 1977 Voyager Program, American scientists launched a spacecraft that contained a recording of images and sounds from various cultures on planet Earth.

If the message was to be sent today, what would you include?
