On May 23, 2010, as it was hurtling toward the boundary between our solar system and interstellar space, the Voyager 2 space probe, having traveled 10 billion miles (16 billion kilometers) over 33 years, suffered a strange malfunction.
Or, at least it seemed to be a malfunction at first. Voyager 2’s flight data system, responsible for formatting the probe’s data so that it can be sent back to Earth, started transmitting back data in a language the scientists couldn’t recognize. According to NASA planetary scientist Kevin Baines, it was “just about 10 billion miles away from the Earth and all of the sudden it starts sending data in the language we don’t understand.
"It can be called as an alien language.”
